## 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.
# set these as you wish: proxy port...
