This filter simply blocks access to certain pages.
The action parameter specifies the access blocking method.
Format:
action = disconnect action = redirect:URL
The problem is that when redirect happens, Foxy doesn't know content type of the requested resource. It will try it's best to guess it by path extention and using some heuristics, but it still may get it wrong. As a result, for example, your browser may show a broken image icon. This may mean that Foxy couldn't guess content type by the blocked resource's URL and served null.html instead.
