Caddy Module: http.handlers.cache

Development repository of the caddy cache-handler module.
This is a distributed HTTP cache module for Caddy based on Souin cache.

[!WARNING] Since v1.7.0 Souin implements only one storage. If you need a specific storage you have to take it from the storages repository and add it either in your code, during the build otherwise.
(e.g. with otter using caddy) You have to build your caddy module with the desired storage xcaddy build --with github.com/darkweak/souin/plugins/caddy --with github.com/darkweak/storages/otter/caddy and configure otter in your Caddyfile/JSON configuration file.
See the documentation about the storages.
