How to do a 301 Redirect in WebMatrix?

Hi I am working in Web开发者_开发百科Matrix and I am getting the error:

The page contains multiple canonical formats.

This happened when I ran an SEO Report on the site. I am getting the error with www.sitename.com and www.sitename.com/Default.aspx.

I know that I need to do a 301 redirect, but if possible how is this done inside of WebMatrix?

Response.RedirectPermanent(location)

or

Response.StatusCode = 301;
Response.RedirectLocation = location;
