Abstract ancestor for server dispatcher components, which own the actual HTTP server and serve the Sparkle server components connected to them.
Remarks
When the dispatcher is activated, it asks each connected server component to create its server module, registers the modules in the HTTP dispatcher and starts the server. Descendants implement the start and stop logic for a specific server type.
Event fired after the modules of the connected server components have been added to the HTTP dispatcher, allowing registration of additional custom modules.
