Hello,
We have a strange problem with displaying banners in Internet Explorer. For example, banners that are included on websites fromhttp://pubads.g.doubleclick.net/gampad are not displayed using TMG as proxy filter.
I can see an error in logs, but I don't know why it happens, because few log entries later the same URL gets allow on the same rule, because user IS authenticated:
Denied Connection ee 2/13/2013 12:30:39 PM
Log type: Web Proxy (Forward)
Status: 12209 Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied.
