Sjoerd Mulder created ZEPPELIN-3080:
---------------------------------------

             Summary: Duplicate Date header on every request
                 Key: ZEPPELIN-3080
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3080
             Project: Zeppelin
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.7.3
            Reporter: Sjoerd Mulder


Currently every request contains a duplicate Date header and one of them is not 
according to RFC causing some third-party services to report issues like:

{{Illegal response header: Illegal 'Date' header: Invalid input 'd', expected 
", " or ' ' (line 1, pos 4):
Monday, November 27, 2017 2:42:53 PM UTC
   ^}}

Found the cause in CORSFilters which adds the Date header too which is actually 
responsibility of the container (Jetty)
