Your next step is to tell Traffic Server about the plugin by
adding the following line to the plugin.config
file. Since our simple plugin does not require any arguments, the
following plugin.config will work:
# a simple plugin.config for hello-world hello-world.so
Traffic Server can accommodate multiple
plugins. If several plugin functions are triggered by the same event,
then Traffic Server invokes each plugin’s function in the order each was
defined in the plugin.config file.
