Busted!

Saves you from asking "have you emptied your cache?". Features

• Safe to leave running on live sites.
• Only refreshes browser cache for a file if it has been modified.
• Resolves Content Delivery Network (CDN) issues. No need to purge CDN cache.
• Multisite compatible.
• "Just works" — no configuration necessary.

Requirements Requires scripts use any of the below functions to load. Almost all files meet these requirements. The only case it doesn't account for is when URLs are hard-coded. This shouldn't ever be done, since it can break sites for other reasons.

• wp_enqueue_style
• wp_enqueue_script
• get_stylesheet_uri
