Difference between Response.Redirect and Server.Transfer?

Response.Redirect

• The page is redirected permanently.
• Used to navigate within the same application as well as navigating from one application to another application.
• The URL is changed because the processing of the second page is done on the second page, not on the first page from where we redirected.
• We can bookmark the page because the full address is shown in a browser URL.
• An extra round trip happens to the server.
• It is used in HTML, ASP and ASP.Net pages to navigate from one page to another.

Server.Transfer

• The Page is not redirected permanently.
• Used to navigate within the same application, not outside of an application.
• The URL is changed because the processing of the second page is done on the same page, without navigating on the second page.
• We cannot bookmark the page because the full address is not shown in a browser URL.
• An extra round trip does not happen to the server; because of this it saves server resources.
• It is only used to navigate within an ASP or ASP.Net page, not within HTML pages.
