Does it work? Well, sort of...
Here's my first attempt:
$ cat ~/inst/23/conf/conf.d/proxy-fcgi.conf
ProxyPass /info fcgi://127.0.0.1:9999/
$ support/fcgistarter -c ~/myhg/apache/fcgid/apps/info.pl -p 9999
(uh, fcgidstarter needed a fix to work on my system)
$ cat ~/myhg/apache/fcgid/apps/info.pl
#!/usr/bin/perl
use strict;
use CGI::Fast;
my $count = 0;
while (my $q = CGI::Fast->new) {
print("Content-Type: text/plain\n\n");
print("Process ID: $$; Count is: " . ++$count . "\n");
print "VHOST: $ENV{'VHOST'}\n";
print "WHO: $ENV{'WHO'}\n";
print "User-AgenT: $ENV{'User_AgenT'}\n";
}
It worked for a few requests, after which the Perl FastCGI engine got
out of sync and blocked in read().
Perhaps others have had better results? (Yeah, I should shut up and
find the problem.)

You'd want to set FCGI_WEB_SERVER_ADDRS as the FastCGI app process is
created, not during request context (PassEnv), since you're trying to
validate what happens in the request context.
