which includes the option

       -pauth=ID:PASSWD
              set  authorization  ID and password for a protected proxy 
                server at startup.  Be sure to pro­
              tect any script files which use this switch.

and the environment variables

       PROTOCOL_proxy      Lynx supports the use of proxy servers
                           that  can act as firewall gateways and
                           caching servers.  They are  preferable
                           to  the  older  gateway  servers  (see
                           WWW_access_GATEWAY, below).  Each pro­
                           tocol   used   by  Lynx,  (http,  ftp,
                           gopher, etc), can be mapped separately
                           by  setting  environment  variables of
                           the  form  PROTOCOL_proxy  (literally:
                           http_proxy,  ftp_proxy,  gopher_proxy,
                           etc),                               to
                           "http://some.server.dom:port/".    See
                           Lynx  Users   Guide   for   additional
                           details and examples.

       WWW_access_GATEWAY  Lynx  still  supports  use  of gateway
                           servers, with  the  servers  specified
                           via   "WWW_access_GATEWAY"   variables
                           (where "access" is lower case and  can
                           be "http", "ftp", "gopher" or "wais"),
                           however most gateway servers have been
                           discontinued.   Note  that  you do not
                           include a terminal '/'  for  gateways,
                           but do for proxies specified by PROTO­
                           COL_proxy environment variables.   See
                           Lynx Users Guide for details.
