Re: [twsocket] HttpServer and Server-push?
Why don't you announce it on your web site and this list with an announcement? It is announced since we are talking about it. But obviously, you used the wrong conversation and the wrong subject. Please note that I have not said that I will do it. Let's first see how much money we can collect. This is a works requiring probably a few hundreds of work hours which can be inserted in spare time and as such require a lot of money for peoples like me who earn their living by programming. Remember, most of ICS is a subproduct of my own business. I have not developped ICS for fun or because I didn't know what to do of my time. Instead, I programmed actual real world application requiring TCP/IP protocol support and I was kind enough to share that part of my work. As far as I know, this is the same for other major contributors to ICS. Thanks to them. -- 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] HttpServer and Server-push?
Sorry Angus, This is probably where the confusion (for me at least) is. I need to be able to get to the posted data from the incoming request before I can determine what to send back. Setting the flag to hgWillSendMySelf prevents the PostedData event from firing. I presume there is another way to get to the posted data apart from the method demonstrated in the webserver demo?

I presume there is another way to get to the posted data apart from the method demonstrated in the webserver demo? Not looked at what the demo does for a long time, but there are numerous 'AnswerXXX' options in the server for returning information, I suggest you start with the simplest which is Answer404 or Answer501, then move on to sending your own answer page. I'll look at updating the web server demo with my delayed response to slow down hackers (using a timer) and repeated updating page, but might not be today.

Re: [twsocket] HttpServer and Server-push?

Does anyone have a working example of this I could look at? An example of what, a web server? Or use of a timer? I actually added a timer to my own web server yesterday, to delay sending a 404 error by 30 seconds to any hackers that try and open a PHP page, to slow down their probing.

[twsocket] HttpServer and Server-push?
Hi everyone, I'm very new to ICS as I've primarily used Indy in the past. I'm currently investigating if I can open a HTTP connection using a THTTPCli to a THTTPServer and keep the connection open until I chose to close it (keep-alive?). I then need to be able to send HTTP messages (xml documents) back from the server to the client periodically or as and when I need to, down the already open connection. The client still needs to be able to respond to these messages. I'm having great difficulty getting this to work in Indy so I though I'd ask if this was possible using ICS before I spend a lot of time experimenting! As I've mentioned, I've virtually no experience with ICS at this point, so if you have any examples or suggestions On how to achieve this, I'd be very appreciative.

Re: [twsocket] HttpServer and Server-push?
I then need to be able to send HTTP messages (xml documents) back from the server to the client periodically In the GetDocument event, for your specific path/URL you need to set: Flags := hgWillSendMySelf; RemoteClient.KeepAlive = TRUE; so the server does nothing more but leaves the connection open, and start a client timer which builds and sends the document periodically using AnswerPage, AnswerString or AnswerStream depending on how much work you do yourself. Remember that ICS is async, so the server is blocked while processing events like GetDocument, that why you need a timer to send your responses, not a never ending loop as in an Indy thread.

Re: [twsocket] HttpServer and Server-push?
Angus, So it does sound like this is at least possible :) Unfortunately my inexperience with ICS is now going to Show rather quickly. I've been looking at the Webserver demo that ships withICS as a basis of what I'm try to achieve. Please forgive my questions if they are somewhat newbie! You wrote, In the GetDocument event, for your specific path/URL you need to set: Flags := hgWillSendMySelf; RemoteClient.KeepAlive = TRUE; So, do I need to do the same for PostDocument? The webserver example uses PostDocument and PostedData. The PostDocument event in the demo requires the Flag parameter to be set to Flags := hgAcceptData before the PostedData event fires. Changing this to Flags := hgWillSendMySelf prevents this from happening. So how would I get the posted data with this change? Apologies if this is way off the mark, ICS is quite different from Indy ;) Thanks for your valuable input!

Re: [twsocket] HttpServer and Server-push?
So, do I need to do the same for PostDocument? The webserver example uses PostDocument and PostedData. Yes, you have to handle the different methods yourself, although HEAD and GET can use the same handle, just don't send any data with HEAD. The PostDocument event in the demo requires the Flag parameter to be set to Flags := hgAcceptData That effectively means end of request and close connection if no KeepAlive with no response the client.
