Well, sort of, but why wouldn't you want to use the tools that are designed
to handle this?
You are sending an HTTP GET request, which is exactly the same as entering
the URL in your browser's command line. EXACTLY the same. That request
will be read by your web server and converted to a CGI request for your
Python program (assuming the serverPage points to a Python script). If you
pass parameters with the URL, you will need to parse those parameters, and
the "cgi" module already knows how to do that.
You don't actually have to use FieldStorage. You can just say this:
import cgi
q = cgi.parse()
which returns the parameters as a simple dictionary.

There are few other mechanisms available in Javascript to do this.
