The ruleset Asymmetric-Publications.xml (aka "Asymmetric Publications (partial)") attempts to rewrite all URLs under *.kingdomofloathing.com to HTTPS. If you log into the site with this rule in effect, you will be taken to https://www.kingdomofloathing.com/game.php, which force-redirects to http://www.kingdomofloathing.com/game.php with a <meta http-equiv="refresh"> tag in the HTML (*not* with an HTTP 3xx response code). The ruleset will rewrite this load back to https://, placing the site into an infinite loop. I don't know how much of the site will refuse to be served over HTTPS. It is possible that just blacklisting game.php would make the ruleset work; however, it seems clearly the intention of the site admins to serve only the login page over HTTPS (optionally), so I'd be inclined to follow suit. I was going to inquire about the level of HTTPS support in the site's forums but I can't log in there.
