Comment 5 for bug 1776928

we can support the relative path also, I am not sure exact rational behind to redirect the relative to absolute path which is from history (not when we switched to route) [1]. May be Alex or John remember.

We can support both /v2.1 and /v2.1/ and map those to 'GET': [version_controller, 'show'].

like this? - https://review.openstack.org/#/c/580544/2

Supporting that in backward compatible way can be discussed further.
