Our production server has been logging the dreaded "This is an invalid webresource request" randomly. We use a lot of Telerik controls in this application and the issue would manifest itself to the user as missing background images for Telerik controls. I was able to reproduce the problem on the production server, but not in development.

I was able to solve the problem locally by resetting my instance of IE8 back to default setting, details in this acticle.

So my question is what IE setting would possibly cause this and how can I avoid this problem in the future? Thanks
