FetchMutableRequest

TBD.

TBD.

Specifies, if any, a ReadableStream which holds the body of a FetchRequest. Body data may only be provided when the method for the request allows a body, such as POST, PUT, and so forth.

If the body for this request has already been consumed, this property must return true; if false, the body is still buffered and may be queried.

Specifies the cache mode for the request. The default value is default, which indicates that the browser or executing engine should use sensible and safe defaults.

Specifies whether user credentials should be sent with the request. The default value is omit, which indicates that user credentials (or any other credentials) should be omitted. Server-side, there are no "default" rules for authorization material present on a request; what you send is what is sent, so this property does nothing.

Describes the destination or use profile for the fetched data in a given fetch request/response cycle.

TBD.

Provides a calculated integrity hash value which is expected to be found when calculating a similar value for any data returned from a Request cycle. The integrity value is expected to be well-formed, with a prefix that describes the algorithm used to calculate the hash.

TBD.

Specifies the operating mode for this request, which is derived from the source of the request and applicable security context. This property is typically not used server-side.

Specifies the operating priority for this request, where applicable/supported. This property gives the developer a chance to express the relative priority of a given request, or to understand the estimated priority for an incoming request.

Describes how redirects are to be handled in response to this request. Only makes sense when expressed on an outbound fetch request instance.

Indicates the referrer value for an outgoing request in a browser. Typically not used server-side.

Indicates the referrer-policy which is active for this request. Typically not used server-side.
