Eduardo Molteni's answer works, except for one thing. It actually passes the browser a 302 instead of a 301.

I believe instead of:

Context.Response.StatusCode = 301 
Context.Response.Redirect("/something/") 

it should be:

Context.Response.StatusCode = 301 
Context.Response.RedirectLocation = "/something") 

The response.redirect is basically interrupting what you were setting up with the Response.StatusCode and the browser ends up getting a "302 Found".

I'm not really sure how search engines handle a 302 vs a 301 so maybe its not an issue. It seems to me though that a true Permanent Redirect (301) would be preferred.

For those on v4 of the framework, there seems to be a new option:

Response.RedirectPermanent("/something")

I haven't tested this, but I'm assuming it provides a 301 as the status code. Details here: HttpResponse.RedirectPermanent
