+Note: No default agent configuration is configured by default.
+To enable it, set `config.agent` to a valid http Agent (i.e. https://nodejs.org/api/http.html#http_new_agent_options)

+```javascript
+var SplunkLogger = require("splunk-logging").Logger;
+var Agent = require('http').Agent
+var agent = new Agent({ keepAlive: true })
