Field	Description
updateMask	object (field-mask) A comma-separated names off ALL fields to be updated. Only the specified fields will be changed. The others will be left untouched. If the field is specified in `updateMask` and no value for that field was sent in the request, the field's value will be reset to the default. The default value for most fields is null or 0. If `updateMask` is not sent in the request, all fields' values will be updated. Fields specified in the request will be updated to provided values. The rest of the fields will be reset to the default.
authority[]	string New list of domains to attribute to the virtual host. The host is selected to process the request received by the load balancer if the domain specified in the HTTP/1.1 `Host` header or the HTTP/2 `:authority` pseudo-header matches a domain specified in the host. A wildcard asterisk character (``) matches 0 or more characters. Existing list of domains is completely replaced by the specified list. If not specified, all domains are attributed to the host, which is the same as specifying a `` value. An HTTP router must not contain more than one virtual host to which all domains are attributed.
routes[]	Route New list of routes of the virtual host. A route contains a set of conditions (predicates) that are used by the load balancer to select the route for the request and an action on the request. For details about the concept, see documentation. The order of routes matters: the first route whose predicate matches the request is selected. The most specific routes should be at the top of the list, so that they are not overridden. For example, if the first HTTP route is configured, via HttpRoute.match, to match paths prefixed with just `/`, other routes are never matched. Existing list of routes is completely replaced by the specified list, so if you just want to remove a route, make a VirtualHostService.RemoveRoute request.
modifyRequestHeaders[]	HeaderModification New list of modifications that are made to the headers of incoming HTTP requests before they are forwarded to backends. Existing list of modifications is completely replaced by the specified list.
modifyResponseHeaders[]	HeaderModification New list of modifications that are made to the headers of HTTP responses received from backends before responses are forwarded to clients. Existing list of modifications is completely replaced by the specified list.
routeOptions	RouteOptions New route options for the virtual host.
rateLimit	RateLimit RateLimit is a rate limit configuration applied for a whole virtual host.

timeout	string (duration) Overall timeout for an HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is kept alive for, regardless of whether data is transferred over it. If a connection times out, the load balancer responds to the client with a `504 Gateway Timeout` status code. Default value: `60`.
idleTimeout	string (duration) Idle timeout for an HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is allowed to be idle, i.e. without any data transferred over it. Specifying meaningful values for both `timeout` and `idle_timeout` is useful for implementing server-push mechanisms such as long polling, server-sent events (`EventSource` interface) etc. If a connection times out, the load balancer responds to the client with a `504 Gateway Timeout` status code. If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see `timeout`).
hostRewrite	string Host replacement. Includes only one of the fields `hostRewrite`, `autoHostRewrite`. Value rewrite settings for HTTP/1.1 `Host` headers and HTTP/2 `:authority` pseudo-headers. If not specified, the host is not changed.

any	boolean When any is set, it matches any request. Includes only one of the fields `header`, `remoteIp`, `any`.

HeaderMatcher

Field

Description

name

string

Required field. Specifies the name of the header in the request.

value

StringMatch

Specifies how the header match will be performed to route the request.
In the absence of value a request that has specified header name will match,
regardless of the header's value.

Response

HTTP Code: 200 - OK

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
createdAt	string (date-time) Creation timestamp. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	string (date-time) The time when the Operation resource was last modified. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
done	boolean If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	UpdateVirtualHostMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	VirtualHost The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

UpdateVirtualHostMetadata

Field

Description

httpRouterId

string

ID of the HTTP router that the virtual host is being updated in.

virtualHostName

string

Name of the virtual host that is being updated.

Status

The error result of the operation in case of failure or cancellation.

Field	Description
code	integer (int32) Error code. An enum value of google.rpc.Code.
message	string An error message.
details[]	object A list of messages that carry the error details.

VirtualHost

A virtual host resource.
For details about the concept, see documentation.

Field	Description
name	string Required field. Name of the virtual host. The name is unique within the HTTP router.
authority[]	string List of domains that are attributed to the virtual host. The host is selected to process the request received by the load balancer if the domain specified in the HTTP/1.1 `Host` header or the HTTP/2 `:authority` pseudo-header matches a domain specified in the host. A wildcard asterisk character (``) matches 0 or more characters. If not specified, all domains are attributed to the host, which is the same as specifying a `` value. An HTTP router must not contain more than one virtual host to which all domains are attributed.
routes[]	Route Routes of the virtual host. A route contains a set of conditions (predicates) that are used by the load balancer to select the route for the request and an action on the request. For details about the concept, see documentation. The order of routes matters: the first route whose predicate matches the request is selected. The most specific routes should be at the top of the list, so that they are not overridden. For example, if the first HTTP route is configured, via HttpRoute.match, to match paths prefixed with just `/`, other routes are never matched.
modifyRequestHeaders[]	HeaderModification Deprecated, use route_options.modify_request_headers.
modifyResponseHeaders[]	HeaderModification Deprecated, use route_options.modify_response_headers.
routeOptions	RouteOptions
rateLimit	RateLimit RateLimit is a rate limit configuration applied for a whole virtual host.

HttpRouteAction

An HTTP route action resource.

Field	Description
backendGroupId	string Required field. Backend group to forward requests to. Stream (TCP) backend groups are not supported.
timeout	string (duration) Overall timeout for an HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is kept alive for, regardless of whether data is transferred over it. If a connection times out, the load balancer responds to the client with a `504 Gateway Timeout` status code. Default value: `60`.
idleTimeout	string (duration) Idle timeout for an HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is allowed to be idle, i.e. without any data transferred over it. Specifying meaningful values for both `timeout` and `idle_timeout` is useful for implementing server-push mechanisms such as long polling, server-sent events (`EventSource` interface) etc. If a connection times out, the load balancer responds to the client with a `504 Gateway Timeout` status code. If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see `timeout`).
hostRewrite	string Host replacement. Includes only one of the fields `hostRewrite`, `autoHostRewrite`. Value rewrite settings for HTTP/1.1 `Host` headers and HTTP/2 `:authority` pseudo-headers. If not specified, the host is not changed.
autoHostRewrite	boolean Automatically replaces the host with that of the target. Includes only one of the fields `hostRewrite`, `autoHostRewrite`. Value rewrite settings for HTTP/1.1 `Host` headers and HTTP/2 `:authority` pseudo-headers. If not specified, the host is not changed.
prefixRewrite	string Replacement for the path prefix matched by StringMatch. For instance, if StringMatch.prefixMatch value is `/foo` and `prefix_rewrite` value is `/bar`, a request with `/foobaz` path is forwarded with `/barbaz` path. For StringMatch.exactMatch, the whole path is replaced. If not specified, the path is not changed.

maxTimeout	string (duration) Overall timeout for an underlying HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is kept alive for, regardless of whether data is transferred over it. If a client specifies a lower timeout in HTTP `grpc-timeout` header, the `max_timeout` value is ignored. If a connection times out, the load balancer responds to the client with an `UNAVAILABLE` status code. Default value: `60`.
idleTimeout	string (duration) Idle timeout for an underlying HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is allowed to be idle, i.e. without any data transferred over it. Specifying meaningful values for both `maxTimeout` and `idle_timeout` is useful for implementing server-push mechanisms such as long polling, server-sent events etc. If a connection times out, the load balancer responds to the client with an `UNAVAILABLE` status code. If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see `maxTimeout`).
hostRewrite	string Host replacement. Includes only one of the fields `hostRewrite`, `autoHostRewrite`. Value rewrite settings for HTTP/1.1 `Host` headers and HTTP/2 `:authority` pseudo-headers. If not specified, the host is not changed.
autoHostRewrite	boolean Automatically replaces the host with that of the target. Includes only one of the fields `hostRewrite`, `autoHostRewrite`. Value rewrite settings for HTTP/1.1 `Host` headers and HTTP/2 `:authority` pseudo-headers. If not specified, the host is not changed.
rateLimit	RateLimit RateLimit is a rate limit configuration applied for route.
