How to get dataPath in web player?

Unity Engine
1 
GUI.Box(new Rect(100, 100, 600, 30), "" + Application.dataPath);

After I build this with “web player” mode,it showes “file:/”.
How could I get the path that the “xxxxx.html” placed?

Which is correct.

You can not access the local computer in any way in the webplayer!
file:// System.IO, System.Environment and a few other things are disabled in the webplayer
