Is it possible to turn off the option in config to prevent the error shown in the link?: http://insidecsharp.blogspot.com/2008/08/iis-7-community-server-tag-problem.html When I visit a certain on my site (http://www.theplaygrounds and then my cv - word), I get the same error. My cv is a word document which I want to open and I basically redirect to (Response.Redirect(string Url) in C#). How can I do this? (I know this sounds basic and is partly a web development question). Thanks
