Find Website Name from a web application

I have two web site sites on IIS 7 (Default, Custom). Both Sites host the same web application.

Some of the web application behavior changes depending under what web site it is running. Is there a way for the web application to find out what is the name of the WebSit开发者_JS百科e under which it is handling the current request.

Thank you Imran
