Re: Re[2]: [twsocket] Connection not closed in WebServer with IE
This doesn't compile, FKeepAlive isn't defined.
You defenitely lack the latest release.

In THttpConnection.AnswerStream, add the following block just after the
lines with Content-Length:
if FKeepAlive then
PutStringInSendBuffer('Connection: Keep-Alive' + #13#10)
else
PutStringInSendBuffer('Connection: Close' + #13#10);
Tell me if it works without adding the header line in your code.

I analyzed the header files sent by a virtual page and an identical real

Connection: Keep-Alive

You can try this mod into the HTTP server component:

Re[6]: [twsocket] Connection not closed in WebServer with IE
Hello Bruno,
But there is also one other thing, and this I could not track, maybe it's
some setting in the server: the connection remains open after you do the
if ((FVersion = 'HTTP/1.0') and
(CompareText(FRequestConnection, 'keep-alive') 0)) or { Jack }
(CompareText(FRequestConnection, 'close') = 0) then
Shutdown(1);
I checked FVersion, it is always 1.1, so it's a bug in IE :)

Re: Re[2]: [twsocket] Connection not closed in WebServer with IE
I think this is what you meant, no?
Yes, but this code has been updated and there is now a variable FKeepAlive that
keep track of this
connection problem. You should download latest release.

Taking a look at SendDocument, I saw this:
{ *DAVID* Revised this if/then/else }
if FVersion = 'HTTP/1.0' then begin
if CompareText(FRequestConnection, 'keep-alive') 0 then
Header := Header + 'Connection: Close' + #13#10
else
Header := Header + 'Connection: Keep-Alive' + #13#10;
end
else if FVersion = 'HTTP/1.1' then begin
if CompareText(FRequestConnection, 'close') = 0 then
Header := Header + 'Connection: Close' + #13#10
else
Header := Header + 'Connection: Keep-Alive' + #13#10;
end;
I think this is what you meant, no?
Adding these lines, the progress bar disappeared, but the connection
remained open:
if FVersion = 'HTTP/1.0' then begin
if CompareText(FRequestConnection, 'keep-alive') 0 then
PutStringInSendBuffer('Connection: Close' + #13#10)
else
PutStringInSendBuffer('Connection: Keep-Alive' + #13#10);
end
else if FVersion = 'HTTP/1.1' then begin
if CompareText(FRequestConnection, 'close') = 0 then
PutStringInSendBuffer('Connection: Close' + #13#10)
else
PutStringInSendBuffer('Connection: Keep-Alive' + #13#10);
end;

Re: Re[2]: [twsocket] Connection not closed in WebServer with IE
Friday, I went to your site and selected Latest ICS version. Isn't that the latest? Yes, it is. But you have not FKeepAlive variable, so you don't use the latest version (or there is a problem on my website, or there is a caching proxy somewhere). FKeepAlive exists since Apr 16 as the history tells (mod by Bjornar Nielsen). -- [EMAIL PROTECTED] http://www.overbyte.be -- 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
Re: Re[6]: [twsocket] Connection not closed in WebServer with IE
I didn't see how I can close the connection. I always get keep-alive in the request, so the response is also keep alive.

With your header, the server you are developing should show the same behavior Yes you right. Then I see same problem. But there is also one other thing, and this I could not track, maybe it's some setting in the server: the connection remains open after you do the request (the progress bar disappears). This doesn't happen with FireFox. I test it, and see same problem. Also with FireFox. I think this is the real reason of the progressbar, because the server has to close the connection once all data is sent and I assume IE keep progressbar running until end of connection OR 'Connection: Keep-alive'. --- Rgds, Wilfried http://www.mestdagh.biz -- 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 -- 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

[twsocket] TCP-based DNS resolution component?
