It's a Sidewinder, by Secure Computing. The denial has so far been noted in conjunction with loading PDFs in a web page, though there may have been some other instances. The header seems to be generated randomly - I haven't figured out a pattern for it yet, but if you stop requesting the URL for some undetermined period of time, the browser doesn't issue that header again for that URL, and the page/document then loads. It's very strange. The firewall is relatively new to us, but I actually like it a lot. I have not talked with their tech support about this issue, though I might later if I have some time. > > > My users get a message that the page is denied by > > security policy.

I'll take a look at this. Thanks! Kurt
