Server.Transfer v/s Response.Redirect
Response.Redirect involves a roundtrip to the server whereas Server.Transfer conserves server resources by avoiding the roundtrip.
It just changes the focus of the webserver to a different page and transfers the page processing to a different page.
Response.Redirect can be used for both .aspx and html pages whereas Server.Transfer can be used only for .aspx pages
and is specific to ASP and ASP.NET.
With Response.Redirect you can redirect the user to the both type of pages .html or .aspx like below,Response.Redirect(“mypage.html”) OR Response.Redirect(“OtherPage.aspx”) But in case of Server.Transfer you can only work with .asp or .aspx page like below
Server.Transfer(“mypage.asp”) OR Server.Transfer(“OtherPage.aspx”)
Response.Redirect can be used to redirect a user to an external websites. Server.Transfer can be used only on sites running on the same server.
You cannot use Server.Transfer to redirect the user to a page running on a different server.
