What do webservers like Crutchfield.Com use to create this sticky
aspect to their url? I understand that they are likely using a
microsoft product in this example. But i am speaking more to the
methdology for doing this in terms of using apache (and hopefully
perl) to accomplish the same thing in terms of caching pages for
visiters that are tailored to them and session tracking. Likely its
doable already i just missed it in the many perl modules.
