Auth header

A some hostings set all letters in headers to small letters. And we have ‘authorization’, but not ‘Authorization’. Can you please fix it?
Fast fix is adding else one element to headers:
$possibleAuthHeaderKeys = [‘Authorization’, ‘authorization’, ‘HTTP_AUTHORIZATION’, ‘REDIRECT_HTTP_AUTHORIZATION’];

But maybe you set all letters in headers to small, and in you array set all letters to small?

Thank you!
