Functions

func ShiftPath 

func ShiftPath(p string) (head, tail string)

ShiftPath splits off the first component of p, which will be cleaned of relative components before processing. `head` will never contain a slash and `tail` will always be a rooted path without trailing slash. Source: http://blog.merovius.de/2017/06/18/how-not-to-use-an-http-router.html
