docsCheckerBaseURL = http://quickdraw.splunk.com/help
* These are various Splunk.com urls that are configurable.
* Setting updateCheckerBaseURL to 0 will stop the SplunkWeb from pinging Splunk.com
for new versions of itself.
So changing the docsCheckerBaseURL to a local version of the documentation should do the trick. I have not had any need to do this myself so I don't know if you can just point to your internal documentation or if you would need to replicate the "official" Splunk documentation.
