title: Manually create Liferay login url
body: <p>Is there a way to create a Liferay login url if I know the site name, virtual host, username, etc...</p>
  
  <p>I basically want to come up with some javascript that enables third-party sites to create a login box to my site, preferablty to a specific page</p>
  
  <p>Just to clarify, I need a url that will log in the user with the parameters they type in text fields on the third party site. The third party site does not necessarily use Liferay so it cannot have a login portlet</p>
