HttpWebRequest with multiple Set-Cookie

I am trying to login to wordpress using httpwebrequest, but unable to do so, there are multiple set-cookie in the response header, few cookies are lost and so unable to show the dashboard, however i am able to login using sockets, but as my all coding is built using httwebrequest i cannot switch to sockets.

response headers

Please can any one suggest how to use httpwebrequest to the job, do i overwrite httpwebrequest to handle cookies from stream, if yes how do i do it?

On using HttpWebRequest post ("http://mywebsite.net/wp-login.php", "log=user1&pwd=pass1&wp-submit=Log+In&redirect_to=http://mywebsite.net/wp-admin/&testcookie=1"

it returns login page, yes i have checked everything 10 times, and the same works if used with sockets, with manual cookie handling.

th开发者_C百科e cookie in manual socket 'Set-Cookie' returns following:

"wordpress_6e7750f6a474de23330d1b7f0e9990c6=admin%7C1301040547%7C2463ecd9d363899be1129ae53287963c; path=/wp-content/plugins; httponly"

same in httpwebresponse is:

"wordpress_sec_6e7750f6a474de23330d1b7f0e9990c6=+; expires=Tue, 23-Mar-2010 08:12:00 GMT;"

the value is missing here =+

Did you forget to set HttpWebRequest.CookieContainer?

By default, it would be null, meaning no cookies would be sent in request header, and no cookies from response would be preserved for latter usage.

I can only suspect, so I may be wrong. Each HttpWebRequest is a new connection, and so a new session is created. The cookies become invalid because of different session. I think Encoding chunked and keep-alive shows that the current connection is somewhat important.

I believe you're using the same socket in the same connection to send all your cookies.

Hope this explains your problem. If not, a bit of code would be useful for further troubleshooting.
