Read the original article Hit count: 235

The definition can be seen here.

The candidate answer may be tcp and dst port 80,but can tcp and dst port 80 guarantee it's HTTP traffic and includes all HTTP traffic?

It seems not,because some site can be visited by specifying a different port other than 80 this way:

http://domain.name:8080

So my question is: what's the exact BPF for HTTP?
