Hi All!

After checking with packet sniffer that for every created HttpWebRequest /
HttpWebResponse followed by Close() call my box creates new TCP/IP
connection I just wonder if there is a way to use single long lasting TCP/IP
connection with a given server for multiple HttpWebRequest / HttpWebResponse
operations.

Any ideas?

Can you post some code? Reusing a TCP connection is what persistent
connections in HTTP 1.1 (or keep-alive in 1.0) are all about, and these
features are all implemented by HttpWebRequest.

Cheers,
 
By default, HttpWebRequest tries to use persistent connections. Now, if the
server is closing the connection after each request, then the client will be
forced to create a new one.

Also, are you tweaking any connection related properties on the webrequest
object, like: KeepAlive, ConnectionGroupName etc? Depending on what you set
there, it might affect connection reuse also

To answer your question, setting request.KeepAlive=true causes connection to
be reused.
