             Summary: Clarify what is invalid header name
                 Key: WFWIP-284
                 URL: https://issues.redhat.com/browse/WFWIP-284
             Project: WildFly WIP
          Issue Type: Task
            Reporter: Tomas Terem
            Assignee: Darran Lofthouse


Header names should follow rules described here:

https://tools.ietf.org/html/rfc5322#section-2.2

However, rules for custom headers seems to be more restrictive - for example @ or = are not allowed. 

I see that these characters are mentioned in https://tools.ietf.org/html/rfc2616#page-16, but it only says that they should be in quotes. However I am not able to configure header containing them in quotes either.

Is this on purpose? 
If yes, this needs to be mentioned in analysis&documentation. If not, we need to create critical JBEAP jira for 7.4
