  IIS 7.5 404 error when redirecting from ASP.NET to Classic ASP Reply Contact I have Windows 7 x64 Ultimate installed on my development box.  I've done everything needed to get Classic ASP as well as .NET running on my system.  I'm developing in Visual Studio 2008 SP1.  Me web site has a default page that has a frameset on it.  In the frameset, after authorization, one frame redirects from an ASP.NET page to a Classic ASP page.  This returns a 404 error to the screen.  If I copy and paste the URL shown in the error page, I can get to the page just fine.  Of course, since it expects to be in a frameset, it doesn't work quite right.  I do have parameters on the URL (in the query string) but i don't think that's causing the problem.  Has anyone heard of this or have any suggestions?

  Re: IIS 7.5 404 error when redirecting from ASP.NET to Classic ASP Reply Contact  I solved the problem.  It turned out a Junior Developer was attempting to use the XSSProtection dlls from Microsoft.  They were running the URL (with parameters) through URLEncode.  So the 404 error screen showed a correct (decoded) URL, but the ASPX code was not seeing the querystring correctly and redirecting to a page that didn't exist.
