Response.redirect and server.transfer (.NET Interview questions)
differ technically and which scenarios should we use them.Technical difference :- In Response.Redirect the following steps happen :-1 – Client browser sends a signal to the server that he wants to go to
xyz.aspx.2 – Server responds back to the browser about the location of xyz.aspx and tells the client to go to that location.3- Client gets the response and redirects to xyz.aspx.
In server.transfer the the following step happens :-
1 – Client browser sends a signal to the server that he wants to go to
2 – Server redirects to xyz.aspx and send the output to the client.
In other words in response.redirect there is a round trip while in
server.transfer there are no round trips.
The next question what interviewer will ask is so does that mean we should always use server.trasfer and response.redirect is never needed Both of the are useful under different scenarios. Response.redirect is good when we want to go cross domains , in other words you want to redirect fromhttp://www.questpond.com/ to http://www.microsoft.com/. Server.trasfer do not work when you go cross domains.
