XHR requests with Authorization header over HTTPS (both together) don\'t reach the server, using Safari (IOS and MacOS). But it works with IE, C
I also faced a similar problem with safari where 'Authorization' in the header was not sent in the GET request but it ended up in a simple thing.
I simply appended a '/' at the end of the request URL and it worked for me.
for eg: change URL from '/token' to '/token/'.
