DESCRIPTION

Subclass ASP4::RequestFilter to instantly apply rules to incoming requests.

These RequestFilters also work for testing via ASP4::API.

ABSTRACT METHODS

run( $self, $context )

IMPORTANT: Return -1 (or $Response->Declined) to allow the current RequestFilter to be ignored.

Returning anything else...

return $Response->Redirect("/unauthorized/");

...results in the termination of the current request right away.
