Well the "I" might be a server maintainer who is not fully cognizant
of the details of CGI, and would expect something which looks like
a path to a file to be one. Such a maintainer may not, in the best
of all possible worlds, really *need* to know what is going on, but
that won't prevent mail to the developers saying "File /cgi-bin/foo1/foo2
is not in the distribution I got; where is it?"
Also is it really clear that no future caching mechanism will ever
need to parse the URL?

This is something that was not clear to me from reading the spec. I
did not realize that the name "cgi-bin" was in any way special. Is,
in fact, "cgi-bin" going to be a reserved word in http URL's? If so
then my objection about parsing is not well founded. This is easy
enough to parse -- it will still confuse some people though. It also
seems like a rather artificial restriction. Am I correct in my
understanding that this means that any subdirectory of cgi-bin is
inaccessible to a client querying the server?
Could we clarify the CGI spec some more?
1. Is "cgi-bin" a reserved directory name?
2. Can it be anyplace in the directory hierarchy?
3. Can a server have more than one cgi-bin?
and most importantly
4. Is it the case that in any URL containing "cgi-bin" everything
from the second '/' after "cgi-bin" to the end of the URL is always
path info, optionally followed by a ? and a query string?
If the answers to questions 1-4 are all "yes", then I will withdraw my
suggestions. I still think this is a less than optimal syntax, but it
is usable.
