Hi,

You have the irules wiki here : https://devcentral.f5.com/wiki/irules.homepage.ashx

You can also have a look at the LTM policies.

Otherwise, you can use a similar irule : 

    when HTTP_REQUEST {
       if { [HTTP::host] contains "f5.com" and [URI::basename [HTTP::path]] eq "audio.mp3" } {
            HTTP::respond 403 content "Access Denied" Connection Close
       }
    }

I have a question regarding your post, do you want to block incoming request from internet users to your own servers. Or the opposite, use F5 as a Forward Proxy and block outgoing requests to internet websites ?

If you are talking about forward proxy. I suggest to have a look at this code : HTTP_PROXY_REQUEST
