title: Link php login form to another page
body: <p>I have a webpage with a login form that should serve as an interface to log you into a webpage with a different domain. To be clear, I want to enter my username and password on my home page and this then logs me into and redirects my browser to a different web page. That other webpage has login form too. So how do I connect this so that you only login once on my page and you end up as logged in on another page.</p>
