On Demand
As well as being set to run at certain times, Presence also allows Tasks to be accessed "On Demand" from a web server or application. This gives you the powerful option of using Presence to generate dynamic web content.
This is performed through the following mechanism:
- On Demand Client makes a call to the Presence Work Server. This is typically embedded within a Web application server such as Tomcat, Glassfish or Resin.
- Work Server executes the Task, identified by its alias
- Response is sent back to the On Demand Client
