RedirectPermanent Performs a permanent redirection from the requested URL to the specified URL. Once the redirection is done, it also returns http 301 status code to the browser.

In ASP.NET, RedirectPermanent is a method used to perform a permanent redirection (HTTP 301) to a different URL. When a request is made to a particular URL, and it needs to be permanently redirected to another URL, RedirectPermanent is utilized.

Here’s the correct answer you could provide:

“RedirectPermanent is a method in ASP.NET used for performing permanent redirections. When invoked, it sends an HTTP 301 status code to the client, indicating that the requested resource has been permanently moved to a new location. This method is commonly used when you want to redirect users from an old URL to a new URL while preserving search engine rankings and bookmarks. Unlike a temporary redirect, which uses the HTTP 302 status code, a permanent redirect instructs search engines to update their indexes with the new URL. Syntax-wise, RedirectPermanent typically takes the new URL as a parameter and may also accept a boolean value to indicate whether to end the response after the redirection.”
