Provide the error output from the ISA gui - monitoring - logging.

Sounds like you have shagged the basic configuration - check my article first.

Sounds like false positives when using that HTTP filter, or bad/incorrect coding of websites.

I guess you could create an extar rule which does not use HTTP filtering and then define a URL set that is exempt from the HTTP filtering.
