Application.srcValue and Application.absoluteURL doesn't work (at least in Unity 4.3), as these values do not contain anything past the ".unity" bit in the URL.

I needed to read URL parameters myself, so I did some more work to find the solution and created a RequestParameters.cs class that does it for you (just add it to a gameObject and call the string GetValue(string key) function: http://www.previewlabs.com/reading-url-parmeters-from-web-player-builds

This uses Application.ExternalEval to run browser-side JavaScript, and pass the document.location.search value to Unity code through SendMessage().

It's explained a bit more in detail in the article containing the RequestParameters.cs class.
