* `script_path`: path to external script.
+Example:
+```elixir
+config :pleroma, Pleroma.Web.MediaProxy.Invalidation.Script,
+ script_path: "./installation/nginx-cache-purge.example"
+```
+
#### Pleroma.Web.MediaProxy.Invalidation.Http
This strategy allow perform custom http request to purge cache.
* `headers`: http headers. default is empty
* `options`: request options. default is empty
+Example:
+```elixir
+config :pleroma, Pleroma.Web.MediaProxy.Invalidation.Http,
+ method: :purge,
+ headers: [],
+ options: []
+```
