.asp handler mapping for .aspx pages

[hect0r]

I am currently developing in Umbraco 4.7.My client has a requirement to redirect classic ASP pages with the .asp extension to their new pages. I have installed the following package:Manage URL Redirects http://our.umbraco.org/projects/backoffice-extensions/manage-url-redirectsThis packages does exactly what I need with .aspx pages and for those without an extension.However, when it comes to .asp this doesn't work. My first thoughts are that this is because .asp is not set up to map to .aspx pages within the handler mappings configuration within IIS7.In an attempt to resolve this, I have added a new handler mapping to IIS.[*]Add Script Manager[*]Request Path - *.asp[*]Executable - C:\windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll[*]Name - ClassicAspToNetPrior to adding this handler mapping, I was receiving the IIS 404 error page. Now I receive a Server Exception: Failed to Execute URL.Example here: http://redeem.attacat.clients.ketchupdigital.com/test.aspYour help would be greatly appreciated in helping me determine whether it is possible to serve .aspx pages with a .asp extension, and if so, how do I do this?Thanks in advance, David.
