I tried to match http packets to prioritize them but I can't seem to match them. I tried the patterns http, httpvideo, http-rtsp all together but http still was not matched.
At the moment, I have to do a port check (80) to determine if it is HTTP, which is not perfect.
I thought that matching http would be easy. Is there some thing to do to make it work? Matching P2P traffic works just fine but I remember I already had problem detecting smtp in the past (haven't tried since then).
