htmlpage =3D a string respresenting the absolute path of the requested .htm=
l file=20


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 =3D int( htmlpage )

But would that be unique?
