The Tunnel Feature Overview
The security model currently used by most Web browsers restricts a Java client to communicating only with the Web server where the Java classes reside. This restriction requires that your SAS server be installed on the same machine as your Web server. For most enterprises, this is not an optimal configuration. The tunnel feature that we are providing lifts this restriction.
The tunnel feature consists of programs that are installed on your Web server. These programs, called the tunnel feature's server programs, use the Common Gateway Interface (CGI) to receive requests from the Java applet running on a user's browser. The server programs forward the requests to the SAS server for processing. When the processing is complete, the programs return the results to the applet.
