A multiple HTTP web server configuration allows you to create web services across databases and have them appear as part of a single web site. You can start multiple HTTP web servers by using multiple instances of the -xs database server option. This task is performed by specifying a unique port number for each HTTP web server.
In this example, the following command line starts two HTTP web services—one for your-first-database.db and one for your-second-database.db:
iqsrv16 -xs http(port=80;dbn=your-first-database),http(port=8800;dbn=your-second-database)
your-first-database.db your-second-database.db
