code, however in certain situations it's useful to check the status of the
agent. The `http.getAgent()` function allows you to access the agents.
+Options:
+
+- `host`: A domain name or IP address of the server to issue the request to.
+- `port`: Port of remote server.
+- `socketPath`: Unix Domain Socket (use one of host:port or socketPath)
