WebClient HTTPS Credential Problems

[df]

Hi,

I'm trying to download the web page source code from a HTTPS URL, my
code is as follows:

Code:

System.Net.WebClient WC = new System.Net.WebClient();

NetworkCredential Cred = new NetworkCredential();
Cred.UserName = "user";
Cred.Password = "pass";

WC.Credentials = Cred;

System.IO.Stream s = WC.OpenRead
("https://xxxxxx/data.html");
System.IO.StreamReader sr = new System.IO.StreamReader
(s);

string webpage = sr.ReadToEnd();
I get a 401 (unauthorized) exception, and i am 100% sure the
credentials are correct, and work perfectly in my web browser for
the file.

I have tested this code without the credentials, on a standard HTTP
URL and it works fine.

Any ideas what I am doing wrong?

Thanks
Jack

Hi Jack

If you try to use credentials you must be sure the page knows about
credentials. Are you sure you try to access page that use to login MS
Credentials ? Maybe it's just a form and you need to send your user and
password using GET/POST method?

Another them is a "cookies". You need to get cookie from site you try to
log on to and use it during all session.

Thanks for the help, maybe I shoudnt be using credentials, when I
use the URL in my web browser i just get a standard login box pop
up, which i assumed needed credentials. The login box im refering to
is the result of .htaccess/.htpasswd files, Is there a special way
of logging into these?

Thanks again,
Jack

No, .htaccess is the NCSA style HTTP Authentication implementation (e.g.
used by Apache). Using NetworkCredential should work here.

Forms authentication on the other hand usually doesn't make use of HTTP authentication
errors, therefore I wouldn't expect to see a 401 in this case.

If all else fails, and you're able to access the file with HTTP as well,
you might want to use Fiddler or any other debugging proxy/network sniffer
to compare your application's HTTP requests to the ones sent by your browser.
