CHAPTER 7.2 :- PARAMETER PASSING

Passing parameters from one page to another is a very common task in Web development. There are still many situations in which you need to pass data from one Web page to another. One of the simplest and most efficient ways of passing parameters among pages is to use the querystring. Unfortunately, packing data into the querystring via string manipulations can quickly lead to cumbersome and often difficult to maintain code, especially as the parameter list grows. To overcome this problem, I’ve used Session in my project. Session has no. of advantages over the

QueryString some of them are described below

· Query String is client side. But Session is server side.

· The information or data stored in Query String is visible to every one. But in Session it is hidden and can’t be viewed easily.

· Query String can store only a piece of information but in Session we can store the more and more data.The Query String speed never falls as the load increase because it stores a piece of information. But on the other hand Session increase congestion as the loads increase.
