Oh dear, I'm afraid the answer is none of them. In this case,
PATH_INFO should be:


The server should not un-escape PATH_INFO. Otherwise, things
like GET /cgi-bin/a/path%2Finfo do a very wrong thing. I just wrote
on this in more detail, see
I think some bug fixing needs to be done, but we should clarify these
details in the spec, first.

I also concur with the solution of just letting the headers through.
Happily, that change can go along with escaping fixups.

For CGI/1.1 we may want to consider npa (no parse anything) scripts which
get fed everything the client sends and talk directly back to the client.
It's a punt, but it'll at least let script authors do anything
(authentication, experimental things, etc.) until a new version of
CGI catches up with new HTTP/1.0 protocol features.
