When quick-editing a page on episerver - it's detecting a potentially dangerous request from one of the textboxes. Now the content to this text box IS potentially dangerous, but I don't want to validate each request. I've followed the obvious instructions of adding validateRequest="false" to the pages node in web.config and have even added ValidateRequest="false" on the page that I'm running (default.aspx) but the browser still appears to be validating.
Can anyone advise? By the way - I've mentioned that it's episerver CMS because the edit page of default.aspx differs (visually) from the typical default.aspx (although the same file name is listed in the address box).
