Request.clone()
The clone() method of the Request interface creates a copy of the current Request object.
Like the underlying ReadableStream.tee`` api, the bodyof a clonedResponsewill signal backpressure at the rate of the _faster_ consumer of the two bodies,
and unread data is enqueued internally on the slower consumedbodywithout any limit or backpressure.
Beware when you construct aRequestfrom a stream and thenclone` it.
clone() throws a TypeError if the request body has already been used. In fact, the main reason clone() exists is to allow multiple uses of body objects (when they are one-use only.)
If you intend to modify the request, you may prefer the Request constructor.
