             Summary: TR should de-dupe Reponse Headers when sending a Steering response.
                 Key: TC-544
                 URL: https://issues.apache.org/jira/browse/TC-544
             Project: Traffic Control
          Issue Type: Bug
          Components: Traffic Router
            Reporter: David Neuman
            Assignee: David Neuman
            Priority: Minor


If you have a steering delivery service configured and the subordinate delivery services have the same Traffic Router Response Headers defined, you will get multiple Headers in your response.  
For example if you set CORS header on each of the subordinate DSs (e.g. Access-Control-Allow-Origin: *), you will end up with 3 CORS headers in your response.
This could cause an issue with some clients which will try to chain the headers together  (e.g. Access-Control-Allow-Origin: *,*,*).
