change player possition via url

Hey,

I would like to ask a question, how I can communicate with may unity content in webplayer via browser. I mean, how I can avoid creating separate scenes for one game, where I need only to change player position. I created 3D town and made it as a web application now what I need to do that user would be able to navigate in my town from different locations, which I want to set manually. These locations user will be able to choose only by typing dif. url in browser window. I sow little bit about this in Unity Documentation:

http://unity3d.com/support/documentation/Manual/Unity%20Web%20Player%20and%20browser%20communication.html

But for me it didn’t say too much, only what I understood I need to create some arguments (which probably should be my player positions) and by typing arguments tags(names) in the end of my game link, I will be able to change player positions when game will start. Thank you for help Best
