How can I send a 301 Permanent Redirect with ASP.NET?

问题

I need to permanent redirect some pages, and redirect the user to the new URL as well.

This code only sets the correct headers. The user are not redirected.

public static void PermanentRedirect(this HttpResponse response, string newUrl)
{
  response.Status = "301 Moved Permanently";
  response.StatusCode = 301;
  response.AddHeader("Location", newUrl);
}

If I put:

Response.Redirect(newUrl);

at the end, a 302 Temporary Redirect is performed.

How can I 301 redirect the user?

回答1:

Try Response.Flush and Response.End. Redirect says to end the request by sending a 302.

回答2:

Note in ASP.NET 4.0 this is now built-in so you can use the RedirectPermanent() method. e.g.

RedirectPermanent("/newpath/foroldcontent.aspx");

or maybe try ISAPI? it mimicks mod_rewrite and other .htaccess functionality on IIS.
