# Content Cache Operator

A [Juju](https://juju.is/) [charm](https://juju.is/docs/olm/charmed-operators) deploying and managing a static web content cache with Nginx.

This machine charm manages a Nginx instance configured as a content cache. The configuration for the locations of cache is managed with the [Content Cache Backends Config subordinate charm](https://charmhub.io/content-cache-backends-config). Each Content Cache Backends Config charm stores the configuration for a location and the associated set of backends.

This charm should be used for caching static web content. When a client makes a request, this charm checks if the requested content is cached and valid. If not this charm will query the backends hosts for the content to refresh the cache. This process works well for static content that does not change based on the client. For these type of content, the cache can greatly reduce the load on the backend hosts.

The charm simplifies the operation of an Nginx server as a static web content cache. This makes the charm suitable for users looking for a low maintenance way to reduce load on static websites.
