TLC Transients

A WordPress transients interface with support for soft-expiration (use old content until new content is available), background updating of the transients (without having to wait for a cron job), and a chainable syntax that allows for one liners.

Examples

In this simple example, we're defining a feed-fetching callback, and then using tlc_transient with a chain to point to that callback and use it, all in one line. Note that since we haven't used background_only(), the initial load of this will cause the page to pause.
