You can host different Help systems by creating multiple contexts in Tomcat. Contexts refer to websites, where a project can be published. You can configure different instances of RoboHelp Server (on a single installation) to run on each of these contexts. These contexts run on the same IP address and port number but with different context names.
By default, RoboHelp Server creates a single context called robohelp. You can create another context using the Configuration Manager.
