clone() method of the
Request interface creates a copy of the current
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 intend to modify the request, you may prefer the
var newRequest = request.clone();
Request object, which is an exact copy of the
clone() was called on.
In the following snippet, we create a new request using the
constructor (for an image file in the same directory as the script), then clone the request.
var myRequest = new Request('flowers.jpg'); var newRequest = myRequest.clone(); // a copy of the request is now stored in newRequest
