It was what I made...
8080 is an alternative for 80, and 3128 is more used for proxies...
In my opinion, Web Shield should scan this by default, but ok...
Vampiric, from my point of view 8080 is not an alternative for 80 in any way. If you type
http://page.domain.com/ it is always port 80, but truth is that Web servers can run on any port the administrator chooses.
Proxies on the other hand are commonly used in company environments. Frequently they ensure some kind of internet access policy - e.g. users must be authenticated. It's hard to guarantee that all these uncommon precaution are compatible with another proxy - WebShield. I don't think that adding an extra port into the WebShield configuration box is such a hassle for the user (or admin) that has to configure all other programs and browsers to use proxy on 8080 or 3128.
