5. Changelist agent

To watch for changes to the static files, ShimmerCat Accelerator runs a changelist agent.

The file change notification agent has one simple job: to detect changes to static assets which are part of a web application, and aggregate them in a special subfolder __sc_changelist__ using a format which is practical to fetch by a remote web cache.

The agent tracks changes with two coordinating mechanisms: a database of hashes that is updated once every five minutes, and INotify watches.

This agent is independent of your web application, and its installation and configuration should only take a few minutes.

5.1. Install the changelist agent

The changelist agent is an open-source, easily auditable code.

Instructions about about how to run it are together with the sources at address:
