[Kimchi-devel] [PATCH V3 2/5] redirect the URL to login page when session timeout or first login

[shaohef at linux.vnet.ibm.com]

From: ShaoHe Feng <shaohef at linux.vnet.ibm.com>

If the content type is application/json still raise 401 status code.
And let UI redirect to login page.

or the backe redirects to login page directly.
