c# - Response.Redirect HTTP status code

Question

Why is it that ASP/ASP.NET Response.Redirect uses a HTTP-302 status code ("Moved Temporarily") even though in most cases a HTTP-301 status code ("Moved Permanently") would be more appropriate?

Answer 1

Responses with status 301 are supposed to be cacheable, and I don't think you want that behavior for most ASP/ASP.NET redirects.

ASP.NET 4.0 is has the RedirectPermanent method for that if needed.
