>Description:
When attempting to use the UnsetEnv directive, which the docs say "Removes one or more environment variables from those passed on to CGI scripts."
However, the ENV variable that I try to remove is still being passed to the the CGI program.
This is distinctly non-critical, but something that I observed while tinkering with my config files.
>How-To-Repeat:
In httpd.conf, put the line:
UnsetEnv SERVER_NAME
or similar. Then run a CGI program that dumps the environment variables, such as:

#!/usr/bin/perl
print "Content-type: text/html\n\n";
for(keys%ENV){print"$_ => $ENV{$_}<br>\n";}

The environment variable specified (SERVER_NAME) is still being supplied to the CGI.
