307 redirect not handled

[Gavin Panella]

When running example/management/run:

{{{
...

panic: DELETE request failed (307: Temporary Redirect)

goroutine 1 [running]:

I would expect the request to be retried at the new location specified in the response, with the same request method. From Wikipedia:

307 Temporary Redirect (since HTTP/1.1)
In this case, the request should be repeated with another URI; however, future requests should still use the original URI. In contrast to how 302 was historically implemented, the request method is not allowed to be changed when reissuing the original request. For instance, a POST request should be repeated using another POST request.
