Often Need HttpServletRequest instance inside realm
Brought to you by:

I often need an instance of current HttpServletRequest
inside realm.authenticate() method, because decision
may vary depending on current request/session.
Attached patches against version 1.1 are for demo
purpose only, because they break backward compatibility.
However, they are safe, I use them in production for
couple of years.
