When I try to access the same URL from a browser I receive our root list of Categories, so I don't think there's a problem with the URL. The response comes after the login prompt from the staging server which means my IP address hasn't been whitelisted.
Is automatic login (or more accurately automatically validating the tester's requests) in the C# application possible? I don't want to require our test team to log in since that behavior isn't consistent with the production server.
Thanks for any help you can offer!
