The clone()
method of the Request
interface creates a copy of the current Request
object.
Like the underlying ReadableStream.tee
api, the body
of a cloned Response
will signal backpressure at the rate of the faster consumer of the two bodies, and unread data is enqueued internally on the slower consumed body
without any limit or backpressure. Beware when you construct a Request
from a stream and then clone
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.
