func Shift

func Shift(req *http.Request) string

For the path "/abc/anything", Shift sets req.URL.Path to "/anything", and returns "abc".

func WithPath

func WithPath(req *http.Request) *http.Request

WithPath stores req.URL.Path in the context associated with req, and returns the new *http.Request, with the updated context.
