I am using HTTPWebRequest to connect to a server which requires
authentication, then responds with a 302 redirect message, and redirects to
DIFFERANT server, which also requires authentication (the same credentials
as the first server). My problem is I can get my client to authenticate to
the first server, and redirect to the first server, but then when the second
server responds with a 401 authentication required message, HTTPWebRequest
does not try to authenticate again... any suggestions?
TIA

Nick,
My guess is that HttpWebRequest doesn't know it's a different server
returning the 401, so it thinks the authentication failed. Maybe if you turn
off automatic redirections and redirect on your own, the 401 from the second
server will be the only 401 HttpWebRequest sees.

Since you have different servers that are requiring same credentials, you
should use the CredentialCache , instead of NetworkCredenti al on the request.
This is how you do it:
CredentialCache cache = new CredentialCache ();
cache.Add(new Uri( http://server1/path1), "digest", new
NetworkCredenti al("user1", "pass1", "dom1"));
cache.Add(new Uri( http://server2/path2), "digest", new
NetworkCredenti al("user1", "pass1", "dom1"));
req.Credentials = cache;
Now, the webrequest will know that there is a credential for the second
server, and will use those for the second request. Just change the above
lines to suit your needs.

news:Os******** ******@TK2MSFTN GP12.phx.gbl... Yes, that works, but creating a new connection for each redirect drastically slows things down... I was hoping for either a fix for this, or for
this to be confirmed as a bug... or for an explination of the reason it behaves
this way, since IE handles it fine...
Wasn't it going to use two connections anyway? One per server?
If it starts using more than the two, please post the info here. It's
looking like I'm going to need to do the same thing soon.

I'm new to coding in .NET. I am trying to do an asynchronous call in my code using httpwebrequest. This code works perfectly fine on one server, but does not work on another.
