Review Comment:
   > The authentication and authorization handlers take effect after the 
handshake is finished.
   
   AFAIK, AuthN is done as part of the handshake itself. But irrespective of 
that, I think our new handler only executes when a handshake is complete. In 
which case our new handler's code will not execute for non authenticated 
requests, hence, there is no risk (contrary to what I mentioned earlier). Is my 
understanding right here?
