JobRouter offers the possibility to run several instances with one installation. This means that a single installation of the PHP application and services allows running multiple JobRouter instances without the need of another installation for each new instance.
To address an instance via the web service, you simply have to pass the instance information in the URL during the web service call.
web service call without instancing:
http://servername/jobrouter/soapservice.php?wsdl
web service call with instancing:
http://servername/jobrouter/soapservice.php/jr_instance_id/1234/?wsdl
This call addresses the instance with the number 1234. If the instance does not exist, the web service call will not be executed.
