Is HTTPServerUtility.Transfer more convenient than Response.Redirect in site performance in asp.net?

Now I'm reading about the performance and scalability of the .net website.

I read a lot of blog posts and a Microsoft book about performance and scalability.

The latest blog is here .

In this blog poing no.6 talk about
"Use HTTPServerUtility.Transfer instead of Response.Redirect" ..

Is it more useful in website performance and for a point like a blog that

" They should only be used when transferring people to another physical web server. For any transfers on your server, use .transfer! You will save a lot of unnecessary HTTP requests. "

Can someone help me on how it is more useful in performance than response.redirect?

You should not just blindly start using Server.Transferinstead Response.Redirect; they are not just replacements for replacement.

Server.Transferperforms another execution of the "lesson" when the current one is turned off, giving out its output. This saves the Redirect step - the redirect calls the 302 - Movedclient with a new download URL, and then the browser makes this new request. This is what is "saved" when you use Server.Transfer.

In short, you save one round trip with Server.Transfer . But the browser could not get the new URL.

Conclusion: . If you want to index your URLs with search engines or want your users to add URLs, then this Server.Transferwill not help.

Server.Transfer: only helps to hide the URL from the user or browser or search engines.
