SEP 12.1 firewall remote host

Hello,

I need to authorize www.abcd.com/toto_123 in the SEP 12.1 firewall as the remote host.

If I add a rule with Host = Remote DNS Host www.abcd.com/toto_123, will it be correclty used by clients ? I'm not sure with the '/' character...

Thanks in advance,

Regards
