IIS 7.5 on Windows 2008 R2 x64, Classic mode. In ASP.NET 3.5 apps, IIS is concatenating the default error pages (e.g. inetpub\custerr\en-US\500.htm
) with my own custom error pages (as defined in web.config, section customErrors
). It first displays the default one, then my custom page, in the same response.
Obviously, I only want my own custom error pages to show up. How do I prevent IIS from using the default pages? How is it even possible that the two pages are mixed?
