+ `X-Request-Id` header. If set to `true`, that value will be used throughout
+ the code as the request identificator. Otherwise, the sent header will be
+ ignored and the request ID will either be taken from Apache's mod_unique
+ module or will be generated by Mediawiki itself (depending on the set-up).
