How can i get IIS 7 to return my custom error pages for file without extension? I got it working for file with extension, but when the extension is not specified, i get the generic page.
回答1:
Try adding a wildcard application extension that maps to the aspnet_isapi.dll.
Without that mapping, requests will never hit the aspnet dll for processing and the default IIS 404 page will be returned.
回答2:
Well if you are dealing with such a situation you should handle these no extension files and then redirect to your custom error page.
回答3:
IIS 7 supports extension less URLs, you can use this with combination of Urlrewriting.net
here is very good article about achieving what you want.
