This is up to you to decide. That is, it is part of the application
design that you must decide on. A typical solution is to have a
parameter to your cgi program that specifies the primary key of the
blog post that you want displayed. For example, say you have a cgi
program called blogpost.cgi. The URL blogpost.cgi?id=1 would display
the blog entry with the id (primary key) 1. You have to write the code
to interpret this parameter in an appropriate way.
