500 when login via API using C#?

I am writing an application in C# 2.0 to consume the Redmine API. An exception is thrown when an HttpWebRequest is sent with the message The remote server returned an error: (500) Internal Server Error.

Checked the log in Redmine and got this:

Processing AccountController#login (for 192.168.1.10 at 2011-03-30 14:46:58) [POST]
  Parameters: {"back_url"=>"http://redmineserver/news?format=atom", "action"=>"login", "username"=>"foo_user", "controller"=>"account", "password"=>"[FILTERED]"}
Rendering template within layouts/base
Rendering common/error (500)

Looks like the application doesn't really happy with the request. Any ideas?

Have a look at your Redmine logs, there should be an error trace in there.

What I don't understand is why you get to the login page if you say you want to use the API.

I am trying to authenticate before allowing any other activities. I turn debug on, but still can't see anything that tells what's go wrong.

Problem resolved. It's the URL that I passed in the request did not hit the controller properly.
Passing URL http://redmineserver/login/?format=xml&username=foo_user&password=foo_password and specify text/xml in the content header has resolved the problem.
