Hi,

I've followed http://technet.microsoft.com/en-us/library/cc302655.aspx to block html upload and it works just fine. However, sometimes, I get some invalid blocks when submitting a page to save info... (no file upload).

I tried to install isa 2006 SP1 but it didn't help at all.

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.

Cheers

JJ
