Call silverlight web page with one argument

Is it possible to call a silverlight web page with an argument?

I want to open the web page and send a number so that the web page can display the number and act in consequence.

something like:

http://example.html argument=1

This way the page would know that is being called as the client number 1 and would save its data to a corresponding place in a database.

The main purpose is that with a single web file, at least 10 instances of it can be called, each one knowing that it is different from the others.

Anyway if there is a better way to achieve this behaviour I want to know since I am starting with web technology.

I hope it is clear.
