irules blocking url

Here is a quick example of irule that will match for HTTP host header of (f5.com or www.f5.com) and then look for multiple files (ex audio.mp3, audio1.mp3 etc.)

Code

when HTTP_REQUEST {
switch -glob [string tolower [HTTP::host]] {
    "f5.com" -
    "www.f5.com" {
        switch -glob [string tolower [HTTP::path]] {
            "*/audio.mp3" -
            "*/audio1.mp3" -
            "*/audio2.mp3" {
                HTTP::respond 403 content "ACCESS Denided" Connection Close
            }
        }
    }
  }
} 

Tools that I use: I currently use the F5 iRule editor to help with creating rules. I'm currently looking at eclipse with the f5 plugin, just haven't tried it out yet.
