[xwiki-users] GoogleAds

Hi Everybody! We went live with out XWiki last week, after three months of testing - and there is one issue about XWiki and GoogleAds. Our Firewall blocks Googleads - every time when a user opens XWiki with the internet explorer there ist the security hint that "there is no blocking information for the security certificate available". When I click on "show certificate" I get the information, that the certificate has been issued for googleAds. Does anybody know what XWiki has in common with googleAds and where I can prevent Xwiki from "telephoning" home? The Window with that hint appears everytime when xwiki is opened in a new IE-Window... Thanx in advance... Toby :) - if anyone needs a script for the database-plugin for creating searchable phone-list - just write me :)! Ill send you the source-code
