+## web relay -- a degenerate version of webproxy, usable with browsers that
+## don't understand proxies.  This just forwards connections to a given server.
+## No query logging, no access control [although you can add it to XNC for
+## your own run], and full-URL links will undoubtedly confuse the browser
+## if it can't reach the server directly.  This was actually written before
+## the full proxy was, and it shows.
+## The arguments in this case are the destination server and optional port.
+## Please flame pinheads who use self-referential absolute links.
