link beetween to oracle servers by http

an Oracle (V8.1.6) client-server application is installed on two servers, one in intranet zone, the other in internet zone. I want to update each database with each update done in any base. But I could'nt use SQL (SQL V2, or NET 8) protocol as the client-server beetween the two servers, I must use http protocol.throw a firewall. Could somebody tell me how to do that ?
