Server.Execute and Server.Transfer

Server.Execute Method

• Execute method allows to consider an external page as a subroutine
  
• When the execution flow reaches the Server.Execute call, control is passed to the specified page
  
• Execution of the current page is suspended, and the external page is spawned
  
• Execute method is a more useful alternative to using server-side includes
  
• Execute makes control to return to the calling page once external page has been executed
  

Server.Transfer Method

• Calling Transfer method causes termination of current page processing and executes the specified page
  
• The control never returns to the page that called the Transfer, which is not the case with Server.Execute, where control returns to the calling page
  
• Hence, any code specified after Server.Transfer call, will not be executed
  
• It is efficient for two reasons, first no roundtrip to the client is requested, unlike Response.Redirect
  
• Secondly, the same HttpApplication that was serving the caller request is reused
