If you find something, please let us know!
By the way, the mechanism is in use for year. If there is a flaw, it could
only be in a special corner case otherwise we already fixed it.

Well
I have seen that you UnregisterMessage routine already removes messages from
the queue:
if FHandle 0 then
while PeekMessage(LMsg, FHandle, Msg, Msg, PM_REMOVE) do {loop} ;
Strange.. must be something else, I will keep digging!

Assunto: Shared handles problem
Hello ICS team,
I´m currently using your implementation of shared handles in all my
applications (I have actually removed all AllocateHwnd and changed to use
your implementation in your to share handles between objects and save some
OS resources), and I think that I have found a flaw in the system but I´m
not sure how to fix.
The problem that I´m facing is that Unsent messages are being received
sometimes
After a lot of debugging and testing I think that I have came to
a conclusion:
In my tests, I create many objects and destroy them, so, there are many
operations to allocate handles (From your lib) and deallocate them
What I
could observe is that if I create an object (Allocating a shared message
from your system), send a message to it and destroy it (deallocating this
message), and creating more objects, the message ID that was allocated to a
previous object (already freed) is now allocated to a new object, and the
message that was posted is still not received.. so, when the main thread
actually process the message and tries to dispatch the message, it will be
dispatched to this new object, creating a great mess in the software
So
I´m not expert in your structure.. but could that scenario occur?
Thanks!
Eric

Re: [twsocket] Close connection (destroy) idle clients
Hello, I am using the example OverbyteIcsThrdSrvV3.dpr plus what happens is that the wind ClientDisconnect is called before processing the received data, and so the connection is lost and I can not communicate with the client, it returned me the error 10053 as log below: TcpSrv (c) 2005-2010 by François Piette.

As far as I understand, the client disconnect to fast, without waiting for the server's answer. So you have to look at the client to understand why it doesn't wait the response from the server. Or maybe the client is not supposed to receive a reply from the server, in which case it is perfectly normal to close the communication on his side. And of course the server should not send any reply. If I misunderstood your problem, please try to explain it using other words. Don't forget to illustrate the protocol in use between client and server. -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be http://francois-piette.blogspot.com -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Close connection (destroy) idle clients
WSocket only with WSocketServer WSocketThrdServer and that this problem occurs, it takes is a message exchange (string) between client and server with multiple clients connected simultaneously, the problem with the component WSocket that is working is that if a customer taking disconnect the network cable, I can not check if there is a socket opened in ClientThread to destroy it and thereby leaving many threads created without ... Is this the same issue as the one related in your previous message ? It seems not. But this looks closer to the subject. To close inactive clients, the easiest way is to record the last time a client sent a request and periodically check the client list and close all client which had no more activity since a give amount of time. By the way, why are you using a multithread version ? usually, multithread applied to simply do not scale very well. Using ICS, properly, you can usually serve hundreds of client with only a single thread. It is a bad idea to create a thread for each client, especially if most client are not really active. You should create a thread only to execute lengthy requests a client may send. Any request which execute fast should not have his own thread. And of course, you should not create and destroy threads but instead a thread pool. Correctly handling multithreading is frequently difficult for the unexperimented multithreading developer. All this being said, I have not enough information to be able to give you better advice. I can only stay general. -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be http://francois-piette.blogspot.com -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Close connection (destroy) idle clients
How to implement the time of the last action on the event and then check OnDataAvailable? Assuming you use ThrdSrv: Add a filed in the class TThrdSrvClient which is instanciated for each client connecting. Update this filed for datetime of the last message sent by the client, probably from the Datavaialble event hanlder. Then from the outside, for example using a TTimer triggered avery 30 sec, iterate thru the client list of the server component and check the last message datetime of each client, calling Abort should that time be greater than a given timeout value. -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be http://francois-piette.blogspot.com -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Close connection (destroy) idle clients
I'm doing based on the example MtSrv, would be the best for my case?
Have you looked at the comments in front of MtSrv sample ?
Here is is:
MtSrv is an old sample program
It works OK, but you should use ThrdSrv project
I will assume you'll use ThrdSrv sample program.

Re: [twsocket] TWSocket and data packet length
I need to send a data packet in one chunck. Today the datas are splitted in two chunks, one of 1500 (the MTU limit) and another one for the rest. I'm not able to go over this 1500 limit. I know it's possible because I have another program how does it like this What you ask is to use Jumbo Frames which is available on some gigabit ethernet systems. Jumbo frames are handled by the OS, not Winsock API (TWSocket make use of Winsock API of course). Altough not tested, you should probably do the following: - Set SocketSndBufSize to some large value - Set BufSize to at least the same large value - Send your data as usual. -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be http://francois-piette.blogspot.com -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Resend: TSslSmtpCli...
I have seen TSslSmtpCli mentioned a couple of places but very little data.
Does such a thing exist? Is it part of the ICS-SSL suite?
Sure it exists. Starting from ICS-V7, ICS-SSL is included in the sntadard
distribution. There is no separate source code. For example TSslSmtpCli is
included in the same source as TSmtpCli component. It is enabled when you
define the symbol USE_SSL.
There are also demo programs included in the distribution. See

Re: [twsocket] Wait for

I know how to get HTML with Async via Events but i have no idea how program it so that Main UI thread will wait and then continue.. :) The component has Sync methods as well? Those are based on the Async methods (native) using a wait loop. It is much much better to use only async methods. This requires you develop your application with async in mind. This means you don't write code sequentially but rather use the events. At first glance, asynchronous programming is a little bit more difficult to grasp, but once you get it, you'll see it is really easy and powerful? After all, Windows UI is fully asynchronous and event driven: you never wait that the user click on a button. Instead you handle processing in the OnClick handler. This is exactly the same with ICS component: you start an operation (such as a http get) and then exit your routine. When the result is coming, you get an event triggered (OnRequestDone in the http case). Just like you put the code to handle the click on a button in the OnClick event handler, you put the code to process the request result in the OnRequestDone event handler. To correctly develop an application using the async, event driven paradigm, you'll see that a finite state machine is a very useful pattern (See http://en.wikipedia.org/wiki/Finite-state_machine as a starting point). To make the story short, applied to Delphi, you define an enumerated type with all the states of your application and then use a variable to hold the current state. Once an event occurs, such as a http get request done, you use that state variable to know what to do you the result and to determine what will be the next state. Of course, it is better to split your whole application in sub-problems, each one with his own state machine. This is exactly what ICS components are: state machines applied to specific internet protocols such as the http protocol you use.

[twsocket] Original way of iterating thru all the bits in an integer
Hi ! I wrote an article about an original way of iterating thru all the bits of an integer. This is the kind of fancy code one could write using recent version of Delphi. I would like to apply this kind of code in ICS, but if I do, it wont work anymore with the old D7. The final code looks like this: var OneBit : Boolean; begin for OneBit in TBitIterator.Create(1234) do Write(Ord(OneBit)); end; You can read the article at http://francois-piette.blogspot.be/2013/01/original-method-to-iterate-bits-w ithin.html -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Original way of iterating thru all the bits in an integer
I was just wondering, what would be a practical application of this routine? As you probably don't know, I'm doing a lot of process control with Delphi. And I frequently have to process bit collections. wouldn't it be more efficient to just shift the value to the left directly without the abstraction of the enumerator? Yes, that's what I said in the article. Most abstractions, if not all are always slower than specially crafted code. However frequently efficiency is not the most interesting factor: ease of write and readability of code tend to be more important than speed. Usually, speed isn't an issue when you have an i7 processor at 2GHz as it is when you have a 8 bits microcontroller running at 1MHz :-) And as I said in the article, this code has the advantage of being very simple and help people learn what they can do with an enumerator and how they can use it in their own application. http://francois-piette.blogspot.be/2013/01/original-method-to-iterate-bits-w ithin.html -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

[twsocket] Writing a TIntegerList property with his property editor and enumerator
Hi ! This subject could be considered out of topic here although it might be applied to ICS as well. I have not applied such coding to ICS because currently ICS has to support old Delphi compilers which lacks the required syntax. I wrote a blog article about writing a class to implement a list of integers suitable as a component property (TListInteger isn't suitable for such use) having his own property editor. This TIntegerList merely looks like TStringList but has integers instead of strings. Using the object inspector, you can edit the list of integers. Link: http://francois-piette.blogspot.com/2012/12/tintegerlist-property-and-proper ty.html I wrote a second article explaining how to add an enumerator or iterator to TIntegerList class. Having an enumerator allows you to use the for..in syntax to iterate thru the list.

Re: [twsocket] IcsWndControl
First of all, I would like to congratulate the ICS team for the wonderful job in creating a way to share windows handles for processing messages. I´m now extensively using this mechanism in all our application. Thanks ! One question though, why is the default limit of 100 messages registered per handle? I know that I can specify a different value for it but why is the default 100? What are the consequences if I increase this value to 1000 or even 1? This way I could use even less handles for the whole system, but what are the drawbacks? There is not rule. When I wrote the code, I've done some testing to see the behavior with TWSocket. I selected 100 messages as a result of this informal testing. Actually the best number is application dependent. The more message you have, the more work is to be done by a single thread. But there could be a lot of not frequently used messages and/or a small number of messages used at a high rate. I cannot advice for a value.

Just started to look at the Web Server demo. When I run it I get 10013 Bind error. Any clues as to how to proceed? Error 10013 mean you have no access to some file. Check the OS files hosts, protocol and services (no extension) which shoud be in C:\Windows\System32\drivers\etc Some virus corrupt those files or make the OS think they are at another location. -- francois.pie...@overbyte.be Embarcadero MVP http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] TWsocket and EStackOverflow
I don't see anything obviously wrong there.
Just to be sure, please test one of the sample programs (For example
OverbyteIcsClient7.dproj which is close to your own test) delivered with ICS to
see if they works OK. If not, then you have somehow corrupted your ICS

! ;) Idon't use the wait() procedure !
I make a copy paste of my source code, as you can see, it's really simple: (I
just suppress each event code where there is just a debug lines added to the

Re: [twsocket] TWsocket and EStackOverflow
You should try using Shutdown instead of closing your end. Shutdown ask the
other party to close the connection and you receive the sessionclosed event
when he accept. If you don't receive sessionclosed event, then you may call
Abort.
Shutdown is a graceful close (one partu ask the other to break the connection),
Abort is an immediate termination of the connection whatever the other party
want.

You probably hit that limit. I don't know which ICS version you are using but I suspect you are using an old one because ICS-V7 is sharing the same window (a hidden window used only for his message queue) and you can have much much more connections without tweaking Windows parameters. It is also possible that you don't free the socket after use and after sometimes you have consumed all Windows resources. Use madExcept4 and FastMM4 to help you find the leaks, if any.

If however you are trying to ping a device on the local subnet which is not there (DOS PING shows Destination host unreachable.) , the application returns 1, 0 and then the Reply.RTT shows the correct time it took to fail. It seems to me that this is a bug because the flag returned from ping indicates a success, and the ErrorCode also indicates no errors.

Re: [twsocket] Design principles of WebSockets server for ICS
By the way, I don't really understand the real world use case for such WebSockets in the context of a IC/Delphi/WebServer application. Unless you have to support and existing client application, it is IMO not very interesting. Maybe I'm wrong. The websockets supersede the old AJAX approach with requesting each portion of data by separate http-request. WebSockets allow you to do the same without overheads on HTTP-headers, which may be very large in comparison with your data, if you're exchanging with small data elements. OK, I understand. You want to support existing client. Sounds good to me. To go back to your initial design question, it is probably better to start with the THttpAppSrv component which is by far the most advanced one to build dynamic web application backend.

Re: [twsocket] Design principles of WebSockets server for ICS
Hello Stan, As I understand, you are trying to - or you already have - implement RFC6455, server side (http://tools.ietf.org/rfc/rfc6455.txt). Is that correct ? There are several ways to implement that using ICS. I don't know the best one since I have not read RFC6455 in details. Candidates are TWSocket, TWSocketServer, THttpServer and THttpAppSrv. Gave the candidates in order of inheritance. At first glance, the highest level is the best because you will less reinvent existing code. By the way, I don't really understand the real world use case for such WebSockets in the context of a IC/Delphi/WebServer application.

It is currently implemented as a tcp-server (TWSocketServer without any modifications) with custom descendant of TWSocketClient, which provides all necessary functionality for WebSockets handshaking and data exchange. We could use it in ICS projects right away, but I'm not sure if this is a proper approach. Lets consider an ordinary use-case for websockets: a client is a browser's built-in websocket, and the socket is instantiated by a web-page code. The web-page itself is normally served by a web-server located on the same host which is an endpoint of the websocket connection. So, standard http- port is used by the web-server, and a dedicated tcp-server (for websockets) is required to listen at a non-standard port, which may be not allowed by some firewalls. On the other hand, we can suppose that the web-server is an ICS-based web-server. So, it is feasible to combine web-server and websockets-server in a single component, serving websockets on standard http-port. I think, this is only possible if the current THttpServer component (actually, meaning with the THttpConnection component) is extended and reworked. That is deriving new components from the existing ones will require overriding of most important virtual methods and copy-pasting much of http-related code into the new methods, what is not good. The reason for this is the need to interlace little yet distinctive websocket code fragments with existing code. In other words, it would be necessary anyway to transform such methods as THttpConnection.ConnectionDataAvailable into a highly templatized methods splitted into several new virtual stages/branches each. Are there some other design principles for implementing this? I'd be glad to hear your opinions, considerations on which variant is the best, and suggestions on implementation. If the general consesus is that current design is sufficient for the moment, I'll send the sources to Francois.

Do you think that routing cicle is ok? There is a better way to do that? Can you give any advice about that? How do you solve the issue which can happen if a client is not receiving data fast enough ? The sending socket will buffer data (It is asynchronous on send as well) and all memory could be consumed if you don't kill client which do not receive data, or at least delete some data (the oldest or the newest). Also, with your system, data is duplicated as much as you have clients.

Re: [twsocket] best way for packet routing
For this I configured each client to send about 1000 packets per second of 4 bytes (about 32Kbps). Your bps computation is wrong. You send 4 data bytes, the actual packets on the network are much larger (something like 10 times) ! Have a lokk there: http://sd.wareonearth.com/~phil/net/overhead/ You should avoid transmitting such small packet. It is better to aggregate small packets into larger ones. fSS.Client [i].

Re: [twsocket] Download manager
I am working on a download manager, and using the HTTPMultipartdownloader component. For now I have 5 different HTTPMultipartdownloader components on my form, but I think I should be able to do it with only 1. like HTTPMultipartdownloader[xx] ? It depends on the requirements for your application. A few questions: 1) Do you want to download several files simultaneously or sequentially ? 2) To download one single file, do you want to download it normally or use the several simultaneous connection to download several parts of the same file at the same time ? Question 1 will tell you if you need one (sequential download) or many (parallel download) components. Question 2 will tell you is you need the THttpCli component (normal download) or the MultipartHTTP component (sevral parts of the same file simultaneously. Actually the multipart component is using several THttpCli component to download several parts of the same file at the same time using the HTTP range option. This is useful when you have a host server with a simple bandwidth limitation. Using the multipart component, you'll go much faster. If the host server has an intelligent bandwidth limiter, this won't change anything and if it has no bandwidth limiter, you'll actually slow down the download. Also don't forget that if you download 10 files simultaneously, each one with 10 simultaneous parts, you'll end up with ONE HUNDRED simultaneous connections. Thinks about the required power on your client computer and network infrastructure. By the way, when using appropriate hardware and OS, ICS is able to handle several THOUSANDS simultaneous connections. This won't work with all configurations because of OS or hardware limitation. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Problems with TWSocket and Skype
It is likely that your problem comes from the different programming paradigm between the two libraries. ICS is non-blocking (asynchronous) while the other is blocking. It is possible that you don't follow the rules for asynchronous programming and get problems... There are two very important rules: 1) Never call directly or indirectly the message pump from one of the component event and 2) never forget that all calls to methods - such as Send - are merely requests and that you get control back immediately while your request execute in the background. If you follow the rules, everything will be OK. You can verify by yourself that ICS components are capable of high speed communication with a huge number of simultaneous connections, both client or server side. See the HTTP and FTP client and server to convince yourself. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -Message d'origine- De : twsocket-boun...@elists.org [mailto:twsocket-boun...@elists.org] De la part de robertoschler Envoyé : mardi 7 février 2012 05:07 À : TWSOCKET Objet : [twsocket] Problems with TWSocket and Skype Hello, A couple of years ago I tried using TWSocket with Skype to send audio back and forth between my Delphi 6 application and the Skype client. I never could get it to work until I switched to the Indy components. Since then I've used ICS in several applications they have always worked great. Now I have another application that interfaces with Skype and again I am having trouble trying to get TWSocket to work with Skype. My application acts as a middleman between an external WiFi webcam device relaying audio from its microphone to Skype's input audio port and relaying audio from Skype's output audio port to the webcam device's speaker. I am using ICS on both sides now. TWSocket works just fine with the external WiFi webcam, however, I can't make it work with Skype. The audio going to Skype is frequently jamming up whereby the buffered byte count rises quickly for short durations, enough to make the audio stream going to Skype unusable (calling TWSocket.Send). The socket receiving audio from Skype receives about 11 to 20 data deliveries successfully and then just dies (OnDataAvailable stops firing). The connection stays open, but Skype stops sending audio permanently. Both sockets for the pair of connections are spawned by a listening socket. The way you tell the Skype client to receive audio from your application is to open a socket on a port number of your choice and Listen. You then tell Skype the port number you are using and Skype connects to you on that port. The same goes for the socket you use send audio to Skype. In both cases you Listen and Skype connects to you on the given port. The difference of course being that you repeatedly handle OnDataAvailable() events on the socket that is receiving audio from Skype, and repeatedly call Send() on the socket that is sending audio to Skype. I'd rather keep things ICS all around but I'm close to switching to Indy on the Skype side. I recently found out that Skype uses Indy for its Windows clients. I'm also aware that Indy uses a thread that blocks to do its work as opposed to TWSocket which uses a message loop. Can anyone speculate as to what about Indy's sockets are more compatible with Skype than (at least for me) TWSocket sockets? What could I try to quickly fix this situation, perhaps by more closely emulating Indy's behavior?

Re: [twsocket] Multiple declaration for 'sockaddr'
Just installed BCB XE and with the DVD was the Overbyte package. I have installed it and trying to use it, but get the error: Multiple declaration for 'sockaddr' I know that it is something to do with the winsock file. I have tried to move around with the includes, but no luck. I have also for many years ago read something about a fix for this error. Something about uncommenting something somewhere, but can't remember what. Anyone hwo have a fix for this...? First of all, please download the latest version from wiki.overbyte.be. The version on Embarcadero DVD was prepared with the beta version. It is subject to changes in the final product and has been updated since then. So download the latest version and try again... Also there are already 3 updates available for Delphi/BCB XE. Be sure to install it ! Once those updates have been installed, try the sample applications delivered with ICS. They should work out of the [virtual] box. If not, please report any issue here. Then start your own development. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Client Server connectivity
How does one handle client/server connectivity in a way that avoids needing to do port forwarding in routers? Ie Something like LogmeIn.com. How do they have it so you log into their server and can contact the client machine even behind a firewall? In those applications, you have a central server located on the internet and accessible from everywhere. Then you have two clients: one for the guy which need assistance and one for the guy who provides assistance. The server relay traffic between the two. The clients stay connected all the time to the server and the server never initiate the connection to the client. Another option is to use a plug and play protocol that routers have which allows a computer to open a port forwarding to him. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

The implementation should be delegated to a handling class which could be replaced easily by the developper. It see a mechanism based on metaclass just like ClientClass property use. Or maybe an interface. Technically interfaces are very good. But ICS is class based and introducing interfaces doesn't fit well in the overall design. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] TWSocket in a tread contest without events
Is possible to use TWSocket object without events contest? I want to use a familiar way for me. I like to create a thread for each connection. Not sure I understand your question! Facts: a) you cannot use TWSocket without using events. b) you can use TWSocket in a thread. There are samples of multithreaded programs included with ICS. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Trouble with ICS v7
I use ICS components in a my application. I have a problem with TWSocket and ServerWSocketDataAvailable. Sometimes, when the ServerWSocketDataAvailable event is called and in action, the same event is called again, before the previous instance is terminated. I use line mode, #13#10 as line terminator and BufferIn:= TWSocket(Sender).ReceiveStr(); I not use anything like ProcessMessage or other. Perhaps some code indirectly calls the message pump? For instance ShowMessage(). Nothing. Is because I use a limemode way? No, line mode has nothing to do with that. The symptoms you describe (reentry in an event handler) are ALWAYS caused by calling the message pump, directly or indirectly. You should be able to see where it is called by looking at the call stack if you can manage to put a breakpoint at the time the event handler is reentered. You could compare the call stack at the time of reentry with the call stack when no reentry occur. FYI, anything which display something on screen and wait for user interaction is calling the message pump ! -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

I'm just about to change to HttpServer MIME handling again, to use a look-up list read from the Windows classes registry or a text file) when the server starts, to replace the current hard coded MIME list. It will be editable by the application. The implementation should be delegated to a handling class which could be replaced easily by the developper. It see a mechanism based on metaclass just like ClientClass property use. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
