SSO topology name is hardcoded in knoxauth.js

The topology name for Knox SSO is hardcoded in knoxauth.js file:

var loginURL = "/gateway/knoxsso/api/v1/websso?originalUrl=";

If I create a proper topology file for Knox SSO under the name e.g something.xml then it does not work since the knoxauth.js always posts data to /gateway/knoxsso/api/v1... instead of /gateway/something/api/v1...

It would be better if the loginURL could be determined from the actual URL, e.g. if the login page is loaded from:

/gateway/something/knoxauth/login.html

then the JS would post the request to:

/gateway/something/api/v1/websso?originalUrl="
