Expunging PageSpeed cache

PageSpeed will make a best effort to expire its asset (.css, .js, .png, .gif, .jpg) cache periodically. During periods of rapid changes, automatic expunction may lag behind changes pushed to a server necessitating a manual flush of the cache.

Expunging PageSpeed cache

A PURGE header may be sent to the asset forcing PageSpeed to expunge its cached copy from memory. For example to accomplish this using cURL from the terminal:

curl -v -X PURGE http://web.site/asset/style.css

To expunge every entry under a common URL or on a web site, use an asterisk:

curl -v -X PURGE http://web.site/asset/*
