     1  Enhancement: Add auth protocol based on user agent
     2  
     3  Previously, all available credential challenges are given to the client, 
     4  for example, basic auth, bearer token, etc ...
     5  Different clients have different priorities to use one method or another, 
     6  and before it was not possible to force a client to use one method without 
     7  having a side effect on other clients.
     8  
     9  This PR adds the functionality to target a specific auth protocol based
    10  on the user agent HTTP header.
