Caroline, unfortunately I don't know as I haven't had a need to do it. Maybe someone else will comment. Your best bet may be the MSDN forums.

How can I use NetworkCredentials in my code to connect to a authenticated website, i.e

https://username:password@www.mysite.com ?field1=value1&field2=value2&..

I tried

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://username:password@www.mysite.com ?field1=value1&field2=value2");

req.Credentials = new NetworkCredential("user1", "foo");

HttpWebResponse res = (HttpWebResponse)req.GetResponse();

At dis point i m getting the error - 400:bad request ...

Can someone fix it out... Thanks in advance

Nick, you can have the web app call the middle tier with the identity used by the client if the middle tier is on the same computer if you are using NTLM. If the web app and the middle tier are on different computers, you either need to have NTLM constrained delegation, which most IT departments will not grant, or you need to use Kerberos (aka Negotiate).

So when you say current logged in user is this user the user that has logged into the Web App or the user under which the asp.net app is running?

That is, can you have

End User Login via Internet Explorer to Web App --> Web App invokes Middle Tier with End User Identity?

Dennis, that sounds like an issue either with a firewall or with an internet proxy on the network. To test the latter, try configuring your IE settings not use any proxy (.NET network code uses the IE connection settings, unless you override them in code).

I am trying to call a web service that uses basic authentication. I generated the web client proxy using wsdl.exe (I'm using .net 2.0)

I create a CredentialCache, add credentials to it, and assign the cache to the service.Credentials but am still getting an exception when I call the service (unable to read data from the transport connection: An existing connection was forcibly closed by the remove host"). Do you have any ideas what else might be going on?
