Netscape servers give a Not Found error for any URL with a /../ or /./
segment (for security reasons). Lynx 2.4 and Netscape 2.01 clients (and
presumably others) process these segments in relative but not absolute
URLs, which I believe is what is supposed to happen according to the RFCs.

Expect to see lots of them as things like Netscape Gold get more popular.
It goes to great lengths to use relative URLs always -- that way a
directory structure can be moved from the author's computer to a sever
without translating URLs. I doubt if it ever produces a /./ segment, but
it will happily do /../ segments.
