ContentType¶
Handling Content-Type auto-detection
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 Examples¶
# Enable auto-detection
labels:
- "traefik.http.middlewares.autodetect.contenttype=true"
# Enable auto-detection

kind: Middleware
metadata:
name: autodetect
spec:
contentType: {}
# Enable auto-detection
- "traefik.http.middlewares.autodetect.contenttype=true"
# Enable auto-detection

[http.middlewares]
[http.middlewares.autodetect.contentType]
Configuration Options¶
autoDetect
¶
Warning
autoDetect
option is deprecated and should not be used.
Moreover, it is redundant with an empty ContentType middleware declaration.
autoDetect
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.
