If an ingoing filter returns a reply object then all further processing of the request
should stop. This means that a perform(request) should not occur. If you look at
the code, I believe that the the basic structure is:

    -    apply ingoing filters, stop if a filter returns a non-null reply
    -    if reply is null, perform request
    -    apply outgoing filters

Again, depending upon the request type you can view this code in HttpManager.
