Its Raining (or rather Pouring)

Went to college for next to nothing....decided we ( Harry, louiswu, myself, rythm & theju) will give our seminars on the 24 of this month. Now that gives me something like 22 days to prepare for the seminar as well as write the documentation.

Pretty nice day at Sify too. The last two days have been productive. Harry & theju cleaned up GTK code while I was playing with Sockets and HTTP headers which brings me to this doubt... How do you terminate an HTTP connection ? Say I telnet to LJ, I'd do this :

telnet www.livejournal.com 80
GET /users/fox2mike HTTP/1.1

This will get me my Journal. Now how do I do a proper quit ? What is the command or sequence of \r\n if any that signals a disconnect from the server ?

Can't wait to see the Gulf Air Bahrain GP's qualifying session. In other news, Kimi's bad luck continues, which means there may not be the excitement that guys like Kimi can cause in a race... but you never know. New track, New race :) Would be a nice experience.

I think read returns -1 or 0 or something like that. See the manpage for read. You need to know that the server had disconnected. That's it.

Umm I don't want the server to disconnect (happens with a timeout), I want my system to signal a terminate/quit to the server & the server then closes the connection.

I wanted something like KeepAlive 0 I think that'll do the trick fine.

you're looking for:
Connection: close
as your last header

the default for many servers is connection: keep-alive

just to clarify:
persistent connections means that you can send multiple HTTP requests on the same TCP connection. You send the Connection: close header for the last request, and a Connection: keep-alive (just to be sure) for all others.

Thanks :) i knew that Keep-Alive was for persistant connections & that simply meant that the server would wait for more requests after serving the first & then time-out if nothing further came in.

Connection:Close does exactly what I needed, thanks again :)

And btw KeepAlive:0 doesn't work the same way on Apache 1.3.x as it does on Apache 2.0.x as in on the 2.0.x KeepAlive:0 terminates the connection as well.
