I suggest that this is the correct behaviour. The 302 and 307 status codes indicate that the resource is to be found elsewhere. #bookmark is a location within the resource. Once the resource (html document) has been located it is for the browser to locate the #bookmark within the document. The analogy is this: You … Read more
