in thread Restoring CGI.pm object

Thanks - although doesn't that affect my $ENV{} in the restoring process ?

I would like it if I could refer to the original $cgi->remote_addr() method, and have it work, and not affect the current environment.

    Since remote_addr is exactly 
    sub remote_addr {
    return $ENV{'REMOTE_ADDR'} || '127.0.0.1';
}

    the easiest way to isolate stored ENV is to use local %ENV

    If you check the source for CGI, you'll find that those functions read from the ENV vars populated by your webserver.

      Ah, thats no use to me then. Thanks for pointing that out.

      I will have to use some other way, don't really want to trash my own ENV with values from a previous request.

      Think I will just store a hash of all the ENV values in the original request then, and restore that hash, don't need the $cgi object in that case, since all it does for me is break up the params .

        You can localize changes to the hash... 
        sub my_restornator {
    local %ENV;
    %ENV = restore_env();
    
    # do things with the restored CGI object

    # goes back the way it was after this brace:
}

        If you're really clever, you could possibly make a restoredCGI object, I'm a little unsure on the details. Can it be done with Autoloader + local? Dunno for sure.
