Submitting the Form Directly: Custom Primer URL

If a form-based login must be filled out before accessing a site, the Custom Primer URL can be set to the <FORM ACTION> URL of the login (fully-qualified), with any form variables (e.g. user/pass) filled out in the query string. If the <FORM METHOD> must be POST instead of GET, the URL protocol may be changed to the pseudo-protocol "http-post". E.g.:

http-post://login.acme.com/checkLogin.asp?User=Admin&Pass=open-sesame

would be submitted using the POST method, with the given query-string variables sent as the content. Note that the query-string variables and values should be URL-encoded.
