WebRequest, Connection management

[oliver.wulff]

Hi
My ASP.NET application has to send https requests to other web servers
quite often. I'd like to know how I should manage the connections? Does
the method WebRequest.Create() reuses an existing https connection to the
destination server or will a new one created for each call? Can several
threads use the same instance returned by WebRequest.Create()? If yes,
will the requests be serialized or will they be called in parallel?
This is quite important to me because I have to use HTTPS and don't want
to establish a connection each time. Ideally, I'd prefer one multithreaded
HTTPS connection.
Thanks for your help!

HTTP is stateless, which means that each HTTP request occurs independently
of any others. An HTTP Request is just that - a message sent to a server
requesting something. The "connection" exists only long enough to send the
Request.

You're right that HTTP is stateless. But you need to cache some data in a
user session on the server. The session is identified by url rewriting or
a cookie. This information is sent with each request. I'm quite familiar
with session handling in Java servlets but don't know how it is
implemented in .NET.
I hope that there is a solution because otherwise it won't perform well
with HTTPS.
