Synopsis: Problem using some chat-Sites with proxy State-Changed-From-To: open-closed State-Changed-By: marc State-Changed-When: Sun Jul 6 15:23:11 PDT 1997 State-Changed-Why: The site you give as an example works by not closing the connection to the client so it can keep adding new data. The way the Apache proxy works, it gets the entire document before sending it to the client. Since it never gets the entire document, it will never send it to the client. Unfortunately, I can't really think of a workaround.
This isn't a bug in Apache, but it would be nice if such things worked. At some point the proxy may be changed so it sends to the client while downloading from the server.
