Troubleshooting - IIS7 mime types .asp .aspx

Hi guys

I am attempting to add asp and asp.net mime types to iis7 and want to know if anyone can help me?

I have gained the following error when trying to run my website:
Error 404.3 (not found)
Description: The page you are requesting cannot be served because of the Multipurpose Internet Mail Extensions (MIME) map policy that is configured on the Web server. The page you requested has a file name extension that is not recognized, and is not allowed.
Error Code: 0x80070032
Requested URL: http://localhost/index.asp
Physical Path: H:\blah\My Web Sites\index.asp

I know where to add the mime types but i do not know what the mime type would be... eg for html its text/html

I hope someone can help me!
