     entity is valid, but cache is unwritable and headers cannot be
     updated.  [Colm MacCarthaigh <colm stdlib.net>]

  *) Added TraceEnable [on|off|extended] per-server directive to alter
     the behavior of the TRACE method.  This addresses a flaw in proxy
     conformance to RFC 2616 - previously the proxy server would accept

     [Jari Ahonen jah progress.com, Brad Nicholes]
     
  *) Log the client IP address when an error occurs disabling nagle on a
     connection, but log at a severity of debug since this error 
     generally means that the connection was dropped before data was
     sent.  Log the client IP address when reporting errors in the core

     handler are contained within the authnz_ldap module.  The
