This can easily be bypassed.

We use a similar ACL in conjunction with delay pools in order to limit the
speed at which people can download MP3s and the like during peak hours. I
spotted in the logs that people were getting round this by adding a '?' to
each request, eg 'http://www.example.com/foo.mp3?'

A quick change to the ACL soon solved that one :-)
