  1. Send user credentials via POST method
  2. Receive, Keep and Return a session cookie
  3. Process HTTP redirect (302)

How to test:

  1. Enter admin and 12345 in the form below and press Login
  2. If you see WELCOME :) then the user credentials were sent, the cookie was passed and HTTP redirect was processed
  3. If you see ACCESS DENIED! then either you entered wrong credentials or they were not sent to the server properly
  4. If you see THE SESSION COOKIE IS MISSING OR HAS A WRONG VALUE! then the user credentials were properly sent but the session cookie was not properly stored or passed
  5. If you see REDIRECTING... then the user credentials were properly sent but HTTP redirection was not processed
  6. Click GO BACK to start again
