Simple caching of query results for Views displays. Includes listening for changes/posts/deletions of certain node types.

Views can then use these times to work out whether to serve the view from cached data or not. You can specify which segments you want to be factored into computing the last time content was updated. For example, if your view is of the latest 'Page' nodes, then you can check the boxes to factor in the 'Page' node type, and then further restrict to just nodes that have been updated/created/deleted. Hard limts of min and max lifetimes are available below."),
