17.7 Bypassing the HTTP Server

Although applets can only open network connections to the same machine

they were loaded from, they need not necessarily connect on the same port

(e.g., 80, the HTTP port). So, applets are permitted to use raw sockets,

JDBC, or RMI to communicate with custom clients running on the server

host. 

Applets do these operations in exactly the same manner as do normal Java

programs, so you can use whatever approaches to socket, JDBC, and RMI

programming that you are already familiar with, provided that the network

server is on the same host as the Web server that delivered the applet.
