This file should contain configuration properties necessary for the construction of HTTP client and server objects. + +Upon initialization, the feature first constructs HTTP server and client objects using the properties from its properties file. A healthCheck operation is then triggered. The logic of the healthCheck verifies that *PolicyEngine.manager* is alive, and iteratively tests each HTTP server object by sending HTTP GET requests using its respective client object. If a server returns a "200 OK" message, it is marked as "healthy" in its individual report. Any other return code results in an "unhealthy" report. + +After the testing of the server objects has completed, the feature returns a single consolidated report. + + + .. code-block:: bash + :caption: feature-healthcheck.properties + :linenos: + + ### + # ============LICENSE_START======================================================= + # feature-healthcheck + # ================================================================================ + # Copyright (C) 2017 AT&T Intellectual Property.
