 ## Introduction
 
-Allows a class to define it's own flush functionality, which is triggered when `flush=1` is requested in the URL.
-[FlushMiddleware](api:SilverStripe\Control\Middleware\FlushMiddleware) is run before a request is made, calling `flush()` statically on all

 > [!WARNING]
 > Flushable implementers might also be triggered automatically on deploy if you have `SS_FLUSH_ON_DEPLOY` [environment
