Server.Transfer v/s Response.Redirect

both are used to transfer a user from one page to another page. Both are used for the same purpose but still there are some differences are there between both that are as follows:

1)Syntactically both are different
2)Response.Redirect involves a roundtrip to the server whereas Server.Transfer conserves server resources by avoiding the roundtrip
3)If you are using Server.Transfer then you can directly access the values, controls and properties of the previous page which you can’t do with Response.Redirect.
4)Response.Redirect changes the URL in the browser’s address bar. So they can be bookmarked. Whereas Server.Transfer retains the original URL in the browser’s address bar. It just replaces the contents of the previous page with the new one.
5)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.
6)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.


What is the difference between debug mode and release mode?
Debug and Release are different configurations for building your project. As the name implies, you generally use the Debug mode for debugging your project, and the Release mode for the final build for end users. The Debug mode does not optimize the binary it produces (as optimizations can greatly complicate debugging), and generates additional data to aid debugging. The Release mode enables optimizations and generates less (or no) extra debug data.

Whats the diffence b/w Biuld and Rebuild

Build means compile and link only the source files that have changed since the last build, while Rebuild means compile and link all source files regardless of whether they changed or not. Build is the normal thing to do and is faster.
