Caching means just storing the frequently used itmes in
memory . Caching is a tried and tested technique for
performance improvement.
Two types of output caching,
1.Page output caching:- It adds the response of page to
cache object. Later when page is requested page is displayed
from cache rather than creating the page object and
displaying it. page output caching is good if the site is
fairly static.
2.Page fragment caching:- it parts of the page are changing,
you can wrap the static sessions as user controls and cache
the user controls using page fragment caching.
