NoSessionOpen::check
public function NoSessionOpen::check
public NoSessionOpen::check(Request $request)
Determines whether delivery of a cached page should be attempted.
Note that the request-policy check runs very early. In particular it is not possible to determine the logged in user. Also the current route match is not yet present when the check runs. Therefore, request-policy checks need to be designed in a way such that they do not depend on any other service and only take in account the information present on the incoming request.
When matching against the request path, special attention is needed to support path prefixes which are often used on multilingual sites.
