Simple Cache

Simple cache plugin middleware caches responses on disk.

Configuration

To configure this plugin you should add its configuration to the Traefik dynamic configuration as explained here. The following snippet shows how to configure this plugin with the File provider in TOML and YAML:

Static:

[experimental.plugins.cache]
  modulename = "github.com/iamolegga/plugin-simplecache"
  version = "v0.4.0"

experimental:
  plugins:
    cache:
      moduleName: "github.com/iamolegga/plugin-simplecache"
      version: "v0.3.0"

Dynamic:

[http.middlewares]
  [http.middlewares.my-cache.plugin.cache]
    path = "/some/path/to/cache/dir"

http:
  middlewares:
   my-cache:
      plugin:
        cache:
          path: /some/path/to/cache/dir

Options

Path (path)

The base path that files will be created under. This must be a valid filesystem path. If the path does not exist, it will be created.

Max Expiry (maxExpiry)

Default: 300

The maximum number of seconds a response can be cached for. The actual cache time will always be lower or equal to this.

Cleanup (cleanup)

Default: 600

The number of seconds to wait between cache cleanup runs.

Add Status Header (addStatusHeader)

Default: true

This determines if the cache status header Cache-Status will be added to the response headers. This header can have the value hit, miss or error.

Force (force)

Default: false

This determines if responses without special cache-related headers should be cached. If this is set to true, responses without special headers will be cached for the maxExpiry cache time. If this is set to false, responses without special cache-related headers will not be cached (as in the original plugin). Works only if cachecontrol unable to find any reason not to cache the response (due to headers, method, status code, etc.).
