URL Rewritting

I have been doing URL Rewriting and typical I do this www.foo.com/author/name.aspx but I want to change my URL rewriting to do www.foo.com/name (btw, name.aspx is the name of the author and it changes)

Typically I do this:

public void Init(HttpApplication context)
		{
			context.BeginRequest += new EventHandler(context_BeginRequest);


            

		}

But when the url is www.foo.com/name the event is not popped.  Only popped if I have the .aspx

anyone know a way around this?
