Hello! Here's me again, trying to do strange things. I'm working on a HelpDesk application that should include a Chat function, amongst other things. I want to do it all using HTTP only (that is, no direct connection, everything needs to be pure HTTP). I really want this HTTP-only thing because I want my application to work in places where my clients only have access to the Internet using an HTTP Proxy!
The chat application has 2 basic components: send your text, receive text sent by the other party. The "send your text" is really easy, but the "receive text sent by the other party" part is a bit more difficult, because I can't keep an open connection between client and server, I need the client to pool for text sent from the server! That is, the client will GET a document of the following format: http://myserver.server.ro/getchat?conversation=12346&seq=1 The server should return any available text for the given conversation or an NOP if no text is available. But here's a trick: If there's no text available for the connection I would like to delay returning an NOP until there IS some text available, or until a 10 seconds delay elapses. This would stop the client from going into a bandwidth-consuming busy-loop. Unfortunately THttpServer doesn't include a "MultiThreaded" checkbox like TSocketServer does, and I'm not sure what I should do to Sleep() without actually freezing the server in the process! I might try subclassing THttpServer and setting FWSocketServer.MultiThreaded = True in CreateSocket but I know too little about the internals of THttpServer and ICS in general to understand the consequences of doing this. Any help on the matter is welcomed, thanks. -- Cosmin Prund -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
