Flushing PageSpeed Server-Side Cache

When developing web pages with PageSpeed enabled, it is sometimes necessary to flush the server’s PageSpeed cache to get the system to reload CSS or JavaScript files that have been updated before the cache lifetime expires.

To do this, touch the file cache.flush:

sudo touch /var/cache/mod_pagespeed/cache.flush
