We are just using the "old" redirector method that we used with squid
2.x, it seems to be working correctly most of the time. Just some times
it seems to mess up.

Ah yes :) They have been known to contact me about how to make websense
work with later versions of squid... I don't hold much hope for this,
besides what I am doing is "unsupported" - would you believe they don't
support rhel 5 as an OS platform?

This could easily be the problem - the site is http://www.news.com.au/
it is not the nicest site about, if you refresh a few time or revisit
the page that comes up blank it eventually comes up mainly, I think,
because the ad that websense is blocking has rotated out.
