Status is a container for computed information about the HTTPProxy.

When true, this field disables client request authentication for the scope of the policy.

Context is a set of key/value pairs that are sent to the authentication server in the check request. If a context is provided at an enclosing scope, the entries are merged such that the inner scope overrides matching keys from the outer scope.

ExtensionServiceRef specifies the extension resource that will authorize client requests.

AuthPolicy sets a default authorization policy for client requests. This policy will be used unless overridden by individual routes.

ResponseTimeout configures maximum time to wait for a check response from the authorization server. Timeout durations are expressed in the Go Duration format. Valid time units are “ns”, “us” (or “µs”), “ms”, “s”, “m”, “h”. The string “infinity” is also a valid input and specifies no timeout.

If FailOpen is true, the client request is forwarded to the upstream service even if the authorization server fails to respond. This field should not be set in most cases. It is intended for use only while migrating applications from internal authorization to Contour external authorization.

If you are another controller owner and wish to add a condition, you should namespace your condition with a label, like controller.domain.com/ConditionName.

Name is the name of the header to match against. Name is required. Header names are case insensitive.

Present specifies that condition is true when the named header is present, regardless of its value. Note that setting Present to false does not make the condition true if the named header is absent.

NotPresent specifies that condition is true when the named header is not present. Note that setting NotPresent to false does not make the condition true if the named header is present.

Contains specifies a substring that must be present in the header value.

NotContains specifies a substring that must not be present in the header value.

Exact specifies a string that the header value must be equal to.

NoExact specifies a string that the header value must not be equal to. The condition is true if the header has any other value.

Conditions are a set of rules that are applied to included HTTPProxies. In effect, they are added onto the Conditions of included HTTPProxy Route structs. When applied, they are merged using AND, with one exception: There can be only one Prefix MatchCondition per Conditions slice. More than one Prefix, or contradictory Conditions, will make the include invalid.

RequestHashPolicies contains a list of hash policies to apply when the RequestHash load balancing strategy is chosen. If an element of the supplied list of hash policies is invalid, it will be ignored. If the list of hash policies is empty after validation, the load balancing strategy will fall back to the default RoundRobin.

Local defines local rate limiting parameters, i.e. parameters for rate limiting that occurs within each Envoy pod as requests are handled.

Global defines global rate limiting parameters, i.e. parameters defining descriptors that are sent to an external rate limit service (RLS) for a rate limit decision on each request.

Prefix specifies the URL path prefix to be replaced.

If Prefix is specified, it must exactly match the MatchCondition prefix that is rendered by the chain of including HTTPProxies and only that path prefix will be replaced by Replacement. This allows HTTPProxies that are included through multiple roots to only replace specific path prefixes, leaving others unmodified.

If Prefix is not specified, all routing prefixes rendered by the include chain will be replaced.

Replacement is the string that the routing path prefix will be replaced with. This must not be empty.

Terminal is a flag that allows for short-circuiting computing of a hash for a given request. If set to true, and the request attribute specified in the attribute hash options is present, no further hash policies will be used to calculate a hash for the request.

HeaderHashOptions should be set when request header hash based load balancing is desired. It must be the only hash option field set, otherwise this request hash policy object will be ignored.

HeaderName defines the name of the header to look for on the request.

DescriptorKey defines the key to use on the descriptor entry.

Headers is a list of 1+ match criteria to apply against the request to determine whether to populate the descriptor entry or not.

This field is only respected when you include retriable-status-codes in the RetryOn field.

ClientValidation defines how to verify the client certificate when an external client establishes a TLS connection to Envoy.

This setting:

1. Enables TLS client certificate validation.
2. Specifies how the client certificate will be validated (i.e. validation required or skipped).

Note: Setting client certificate validation to be skipped should be only used in conjunction with an external authorization server that performs client validation as Contour will ensure client certificates are passed along.

EnableFallbackCertificate defines if the vhost should allow a default certificate to be applied which handles all requests which don’t match the SNI defined in this vhost.

Conditions contains information about the current status of the HTTPProxy, in an upstream-friendly container.

Contour will update a single condition, Valid, that is in normal-true polarity. That is, when currentStatus is valid, the Valid condition will be status: true, and vice versa.

Note: This only applies to externalName clusters.
