ContentType

The Content-Type middleware sets the Content-Type header value to the media type detected from the response content, when it is not set by the backend.

info

The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
Therefore, it has no effect against any other Content-Type header modifications (e.g.: in another middleware such as compress).

Configuration Options​

autoDetect​

warning

autoDetect option is deprecated and should not be used.
Moreover, it is redundant with an empty ContentType middleware declaration.

FieldDescription
autoDetectautoDetect specifies whether to let the Content-Type header, if it has not been set by the backend, be automatically set to a value derived from the contents of the response.
