The Logic: Sites generate a unique "token" for every visitor. If you send a login request without the token from that specific session, the server rejects it as an "Invalid Request."

• The Fix: Perform a "GET" before your "POST."
  
• The Workflow:
  
  1. Request 1 (GET): Hit the login page URL.
     
  2. Parse: Extract the
     value
     from the hidden input:
     <input type="hidden" name="csrf_token" value="([A-Z0-9]+)">
     .
     
  3. Request 2 (POST): Send your
     email
     ,
     pass
     , and the
     csrf_token
     variable you just parsed.
