Response.Redirect Definition:

Response.Redirect refers to an HTTP code, which sends the user to a new page updating the address bar and adding the same into the browser track history. You can press the backspace on your browser to go back. 

What is the difference between Response.Redirect and Server.Transfer? 

Server.Transfer is a specialised command, which doesn’t get changed at the address bar. You can’t press the backspace because it doesn’t go back. Response.Redirect asks the online browser to go to another page, on the other hand, Server.Transfer reduces server requests while keeping the URL the same.
