Hidden Frames in AJAX :--
This Technique is a longstanding trick of developers to return information from the server
but keep it invisible to the user.
It uses a standard frameset with two frames to open two separate pages (or more if required),
the first being visible to the user and the second being made invisible by setting its width or height to zero.
The hidden frame can be used to send requests and retrieve data from the server,
but the data is placed in the visible frame only when needed.
