mostly the dynamic pages are created from a database while passing some variables through forms, url etc. like a site showing profiles of its customers passes some variables to the profile page like www.examplesite.com/profile.asp?userid=abcxry etc.

I have also come across some website which don't pass these variables ( may be passing in backgroud) and they create a separate page for every user. The pages are also created Dynamically from the database but they end like www.examplsite.com/user/user134.htm etc.

Does any body understand my point and can help me in this regards.
