Classes

AdditionalResponseHeaders

Sets up click-jacking prevention for HTTP requests by adding HTTP headers for the response

BackendModuleValidator

Validates module access and extends the PSR-7 Request with the resolved module object for the use in further components.

BackendRouteInitialization

Injects the Router and tries to match the current request with a configured backend route. The available backend routes were added in the corresponding dependency injection factories, which load and process the module and route configuration files

BackendUserAuthenticator

Initializes the backend user authentication object (BE_USER) and the global LANG object.

ContentSecurityPolicyHeaders

Adds Content-Security-Policy headers to response.

ContentSecurityPolicyReporter

ForcedHttpsBackendRedirector

Check lockSSL configuration variable and redirect to https version of the backend if needed

LockedBackendGuard

Checks various security options for accessing the TYPO3 backend before proceeding

OutputCompression

Sets up output compression

SiteResolver

Usually called after the route object is resolved, however, this is not possible yet as this happens within the RequestHandler/RouteDispatcher right now and should go away.

SudoModeInterceptor

Middleware that catches any `VerificationRequiredException` (= the current user must verify the access for a particular resource, route, module) by entering their password again; and any `RequestGrantedException` (= the verification process was successful & the user shall be redirected to the URI, that has been requested originally).
