We basically have two layers of filtering implemented...

LEA via BT's Bluecoat Internet Exchange & an Equiinet CachePilot on site.

I'd ideally like to have a program at hand which I could copy a list of websites into which would visit each site and check for a phrase

i.e. Access Denied (policy_denied)

If the phrase was/wasn't found it would feedback appropriately.

Any ideas?
