A DESCRIPTION OF THE REQUEST :
Currently, a JVM cam have at most one 'live' Authenticator object at any
given time; i.e. the one set using Authenticator.setDefault().  This causes
problems in some applications.  I propose that a new method be added to
the URLConnection API:

    void setAuthenticator(java.net.Authenticator auth)
       throws InvalidStateException;

This method would allow an application to bind a specific Authenticator
to an unconnected URLConnection object to be used instead of the JVM-wide
default Authenticator.

JUSTIFICATION :
This method will make it possible to do a number of things that are otherwise
hard to implement in a multi-threaded application.  For example, if a URL has
a 'userinfo' componenent, the application can create a once-off Authenticator
for the URL's username and password and attach it to the URLConnection.  It does not need to worrying about interfering with (or leaking passwords to) other
threads.
