649 - filter action, explained below, which specifies which action the
650 filter is called for

652 - http method
653 - http referer
654 - http path

657 - cgit page

660 HTML for displaying the login form, which POSTs to "/?p=login". When
661 the filter action is "authenticate-cookie", this filter must validate
662 the http cookie and return a 0 if it is invalid or 1 if it is invalid,
663 in the exit code / close function. If the filter action is
664 "authenticate-post", this filter receives POST'd parameters on
