Are you forwarding tp page A and then Page B?

[Chandra Bairi]

It can be to any page but it will be dynamic. it will depend on a variable and some condition

I am still not clear.

Remove the attribute from request scope and store it in session scope. Whenever required pull it from session ans store it in request.

i am not clear as well as what you need to answer my question. firstly let me make you clear that the scope hierarchy i feel is
page
request
session and
application/context.
now I have put a variable(let us say x) in request scope in page A and i am supposed to have it in request scope. From A i can go either to page B or page C. but it i go to page B then i can see that variable i.e. i can just say request.getparameter() but if i go to page C i should not be able to get the current scope variables. i hope this is clear.

I guess you are talking about request attribute and not request parameters.
You can remove the request parameters from the request scope by calling
request.removeAttribute() when yopu forward to page C.

I asked one of my friend and he said if we have to see a variable from request scope then it has to be jsp:forward and if we want to isolate it then it has to be redirect. is that true?

Hi
In A, set the attribute in request scope only when are forwarding to B. Probably you have a condition that decide to forward to B or C. Set the request attribute inside the condition.

If you redirect all request attributes and parameters are lost.
