htmlpage = a string respresenting the absolute path of the requested .html file 


What i want to do, is to associate a number to an html page's absolute path for to be able to use that number for my database relations instead of the BIG absolute path string.

so to get an integer out of a string i would just have to type:

pin = int( htmlpage )

But would that be unique?
