Ajax
AJAX = Asynchronous JavaScript and XML.
AJAX is not a new programming language, but a new way to use existing standards.



Use of Ajax
AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page.

DIFFERENCE BETWEEN AJAX AND CACHING ?
caching is something like..........whenever dot net application get compiled for the first time the info is stored in cache and whenever next time that page is requested dot net provide it from cache....it makes execution fast
Ajax request send to server.
Cache is store the Page in Buffer and when u r frequesnlt request pages are stored in Cache..whenever u again request the page then that not contact to server.

but in AJAX the page can't be refreshed again and again.javascript will contact to server by using XMLHttpRequest() OR ActiveXobject().

Caching Options in ASP.NET
ASP.NET supports three types of caching for Web-based applications:


Page Level Caching (called Output Caching)
Page Fragment Caching (often called Partial-Page Output Caching)
Programmatic or Data Caching
