I have a question, if I open a web page X and that page contains links, Y and Z, to other servers, how many session id will I get when I open X?( I want to check request packets and see which packet is from X and which is from Y and so on)

Dear friend:
session is what belongs to Server, so u cant pass a session from Server to Server normally, u'll have to use something like Database Session & ...
but about ur scenario! I didnt get it clearly but i may send ur request using QueryString.

Thanks. I want to distinguish different request packet which one web site sends to other servers I thought maybe session id become handy! What do you think?

well QueryString will do it great & simple
simple link other servers in QueryString & dont push it anymore!
I'd like to be more specific if i had more detail
