Recently while looking over some FAST for SharePoint labs one of the exercises had you edit a property called:
The production setting for this is “false”, which will make the system do cleanup of a claims cache.
But reading the name and what it actually does is very hard due to using both the words “Allow”, “Non” and “TestingOnly”. You have a positive word, a negative word and a specific case where the property is valid, all in the same name.
The proper name for this should in my opinion be:
where the production value should be “true”. With a comment to explain why you would set this to false, e.g. in a test scenario.
