One (and no more than one) of the functions
	ne_session_proxy,
	ne_session_system_proxy,
	ne_session_socks_proxy,
	ne_set_addrlist can be used to configure
	a proxy server for a given session object.  If more than one
	function is invoked for any given session object, only the
	last call has effect.  If one of the functions is to be used,
	it must be used before the creation of any request object for
	the session.
The ne_session_proxy function
          configures use of an HTTP proxy server for the session, the
          location of which is given by the
          hostname and
          port paramters.  If the proxy
          requires authentication, ne_set_proxy_auth
          should be used.
The ne_session_system_proxy
          function configures the session to use any proxy servers
          specified by the system configuration.  Support for this
          function is platform-specific; if unsupported, the function
          has no effect.
The ne_session_socks_proxy
          function configures the session to use a SOCKS proxy.  The
          version indicates which version of
          the SOCKS protocol should be used.  The
          hostname and
          port parameters specify the SOCKS
          proxy location.  Note that a server with only an IPv6
          address cannot be used with SOCKS v4 or v4A.  The
          interpretation of the other arguments depends on the version
          specified:
| 
 | The usernameparameter
	       must be non-NULL; thepasswordparameter is ignored. | 
| 
 | The usernameparameter
	      must be non-NULL; thepasswordparameter is ignored. | 
| 
 | The usernameparameter
	      may beNULL; if it is non-NULL,
	      thepasswordparameter must also
	      be non-NULL; otherwise, it is ignored.. | 
The ne_set_addrlist function
          forces use of an address and port the a specified list when
          establishing a TCP connection, ignoring the "real" hostname
          and port identifying the origin server for the session (as
          passed to ne_session_create).  The
          origin server's "real" hostname and port will still be used
          in the Host header in HTTP requests.
          When a connection is required, the library will iterate
          through the addrlist list, attempting
          to connect to the address addrlist[0]
          through to addrlist[count-1] in turn,
          until a connection can be established.
