session variable or object

i have some problem with session object:

for example if i define a session variable
and make it equal to a string(i.e session("str")="fgjfkg" )
when i want to use it in another page it's value is equal with nothing
(i.e session("str")=nothing)
is you know how to solve prolem please tell me

thanksHello, make sure session are enabled in the asp.net application you have. Check your web.config file.
Also, make sure that cookies are enabled on ur machine, since sessions will use cookies.

Hello, yes you should, you have to inclide the Session_Onstart method.
