Re: [twsocket] Multithreaded http...
> because there are alot of records to check, i wanted it to be threaded... Well, this is defenitely not a case where multithreading is needed because ICS HTTP component is asynchronous. HTTP component doesn't block ! It automatically handle your requests in the background using events. If you need to handle 100 simultaneous requests, then simply use 100 HTTP components and async methods (GetAsync and the likes) and events (OnRequestDone and the likes). btw: Not all Windows versions are able to handle 100 simultaneous connections ! This is not a limitation of ICS, it is a built-in limitation in some Windows versions. You need a "Windows Server" edition to be able to handle hundreds of simultaneous connections. -- [EMAIL PROTECTED] http://www.overbyte.be - Original Message - From: "Flash Thunder" <[EMAIL PROTECTED]> To: "ICS support mailing" Sent: Wednesday, April 13, 2005 11:09 PM Subject: Re: [twsocket] Multithreaded http... > > - Original Message - > From: "Francois PIETTE" <[EMAIL PROTECTED]> > To: "ICS support mailing" > Sent: Wednesday, April 13, 2005 10:13 PM > Subject: Re: [twsocket] Multithreaded http... > > > > > I'm kinda new in Delphi but i really really need to write some > > > application...

[twsocket] FTP Connection Timeout - how to change
Hi! I have a slow FTP connection (typically the connection lasts about 60 sec using for example Total Commander). I tried to connect using ICS FTP component, but after about 15 sec I receive "Error code 10060 - Connection Timed out". I changed the timeout property of the FTP component to 60, but no changes were seen. Where can I set the timeout value for FTP connection?

Re: [twsocket] Is there a way to download a file in threads?
You seem to be right and I can understand why Apache has chosen threaded way (for UNIX compatibility) but why did MS chose threads? What about I/O optimization. For example async freezes when a buffer of I/O is being read whereas threads to better disk/socket I/O?

Error 10060 is a winsock generated error. There is nothing you can do about it from the component. You have to change TCP/IP registry leys to adapt the timeouts. Note that 15 sec timeout is not the standard winsock timeout. I suspect you have already tweaked the registry.

Be that as it may, discussions of the /design decisions/ that lead to the current state are neither useful nor topical here as they do not relate to the ICS components in the slightest. The current state itself is topical... in as much as it relates to the functioning of the components and no further. All that aside, Francois is the owner of this mailing list.

Re[6]: [twsocket] NOFORMS and TWSocketServer
Thanks Francois for the testing. Arno was right. Once I updated to the latest ICS, the file size went down to 127KB (Delphi 5.) Before I used TWSocketServer it was 61KB. Not sure why it doubled the file size. But it's still a lot better than before, which was over 300KB. I added some lines of code though but I didn't add any other unites. -- Best regards, Jack Thursday, April 14, 2005, 1:52:17 PM, you wrote: AG> Francois PIETTE wrote: >>> I did some further testing. >>> >>> I commented out most of my code so it's not doing >>> anything.

A new ICS version is available. A small bug has been fixed in the HTTP client component that affected authentication with iPlanet Web Proxy Server (found by Mr Bloms and Tomachinsky). A new console mode sample: ConUdpLstn. It is the GUI sample UdpLstn ported to console. It make use on the TConApplication object that is now included in ICS and many of you haven't probably noticed.
