Simulating user load by way of variables in URL String

[Nathan Chandler]

Have application (Front Servlet) that is accessed as follows:

http://www.myco.com/servlet/AServlet?id=12345678

where the id number is something that identifies a user of the system.

Q. Can (and if so how) JMeter be used to generate realistic loading from X different 
users each of which need to have different parameter value where after initial hit 
each user has HttpSession and thus client needs to manage per user cookie info.

Many thanks in advance for information.
