 New Revision: 209632
 URL: http://svn.freebsd.org/changeset/base/209632
 
 Log:
   If the A flag is supplied, http_request() will attempt the request only
   once, even if authentication is required, instead of retrying with the
   proper credentials.  Fix this by bumping the countdown if the origin or
   proxy server requests authentication so that the initial unauthenticated
   request does not count as an attempt.
