Motivation: At the moment if you want to return a HTTP header containing multiple values you have to set/add that header once with the values wanted. If you used set/add with an array/iterable multiple HTTP header fields will be returned in the response. Note, that this is indeed a suggestion and additional work and tests should be added. This is mainly to bring up a discussion. Modifications: Added a flag to specify that when multiple values exist for a single HTTP header then add them as a comma separated string. In addition added a method to StringUtil to help escape comma separated value charsequences. Result: Allows for responses to be smaller.
