The only way to do this currently is to modify Sessions.cc to add the other
ports of interest (search on "80" to see where the additions are needed).
You'll also need to change the capture filter in http-request.bro (or make
your own version that adds the port to capture_filters - that's cleaner).

This is strange - Sessions.cc already treats 8080 (and 8000 and 3128) the
same as 80. Can you provide a trace that exhibits the problem?
