MiscDirectives

Extracts the client's IP from either the X-Forwarded-For, Remote-Address, X-Real-IP header or pekko.http.scaladsl.model.AttributeKeys.remoteAddress attribute (in that order of priority).

Converts responses with an empty entity into (empty) rejections. This way you can, for example, have the marshalling of a ''None'' option be treated as if the request could not be matched.

Rejects if the request entity is non-empty.

Rejects with a RequestEntityExpectedRejection if the request entity is empty. Non-empty requests are passed on unchanged to the inner route.

Inspects the request's Accept-Language header and determines, which of the given language alternatives is preferred by the client. (See http://tools.ietf.org/html/rfc7231#section-5.3.5 for more details on the negotiation logic.) If there are several best language alternatives that the client has equal preference for (even if this preference is zero!) the order of the arguments is used as a tie breaker (First one wins).

Checks the given condition before running its inner route. If the condition fails the route is rejected with a ValidationRejection.

Fails the stream with pekko.http.scaladsl.model.EntityStreamSizeException if its request entity size exceeds given limit. Limit given as parameter overrides limit configured with pekko.http.parsing.max-content-length.

Beware that request entity size check is executed when entity is consumed.

Disables the size limit (configured by pekko.http.parsing.max-content-length by default) checking on the incoming HttpRequest entity. Can be useful when handling arbitrarily large data uploads in specific parts of your routes.
