6.7. HTTP header configuration

When setting or deleting headers, you can use an individual route to modify request and response headers. You can also set certain headers by using route annotations. The various ways of configuring headers can present challenges when working together.

注記

You can only set or delete headers within a Route CR. You cannot append headers. If an HTTP header is set with a value, that value must be complete and not require appending in the future. In situations where it makes sense to append a header, such as the X-Forwarded-For header, use the spec.httpHeaders.forwardedHeaderPolicy field, instead of spec.httpHeaders.actions.

Example Route spec

apiVersion: route.openshift.io/v1
kind: Route
# ...
spec:
  httpHeaders:
    actions:
      response:
      - name: X-Frame-Options
        action:
          type: Set
          set:
            value: SAMEORIGIN

Any actions defined in a route override values set using route annotations.

6.7.1. Special case headers
リンクのコピー

The following headers are either prevented entirely from being set or deleted, or allowed under specific circumstances:

Expand
Header nameConfigurable using Route specReason for disallowmentConfigurable using another method

proxy

No

The proxy HTTP request header can be used to exploit vulnerable CGI applications by injecting the header value into the HTTP_PROXY environment variable. The proxy HTTP request header is also non-standard and prone to error during configuration.

No

host

Yes

When the host HTTP request header is set using the IngressController CR, HAProxy can fail when looking up the correct route.

No

strict-transport-security

No

The strict-transport-security HTTP response header is already handled using route annotations and does not need a separate implementation.

Yes: the haproxy.router.openshift.io/hsts_header route annotation

cookie and set-cookie

No

The cookies that HAProxy sets are used for session tracking to map client connections to particular back-end servers. Allowing these headers to be set could interfere with HAProxy’s session affinity and restrict HAProxy’s ownership of a cookie.

Yes:

* the haproxy.router.openshift.io/disable_cookie route annotation * the haproxy.router.openshift.io/cookie_name route annotation
