What is the difference between Response.Redirect and Server. Transfer in Asp.net

Response.Redirect:-

• Response.Redirect sends message to the browser saying it to move to some different page.
• use Response.redirect to redirect to another website.
• we do not need to preserve Query String and Form Variables from the original request.
• Response.Redirect() can be used for both .aspx and .html pages

 Server.Transfer:-

• Server. Transfer does not send any message to the browser but rather redirects the user
  directly from the server itself. 
• Use server.transfer to navigate within website
• we want to preserve Query String and Form Variables (optionally)
• Server.Transfer() can be used only for .aspx pages and is specific to ASP and ASP.NET.
