Terminable

Optional middleware lifecycle hook for post-response cleanup.

interface Terminable

A plain Middleware only gets to act before $next($request) is called and immediately after it returns — but views/templates render lazily, so the response body isn't actually built yet at that point. Middleware that needs to release or reset per-request state only once rendering has genuinely finished (e.g. an auth adapter's in-memory session state, so it doesn't leak into the next request on a long-lived worker) should implement this interface in addition to Middleware.

shutdown() is invoked once per request, for every middleware that actually ran (i.e. was not skipped via only()/except()), after the response has been fully written. If the request pipeline threw before a response could be produced, $response is null and shutdown() runs immediately rather than waiting on output that will never happen.

Methods
