ajax4jsf Filter should ignore HTTP 304 and other responses <200 or >299
-----------------------------------------------------------------------

                 Key: RF-8277
                 URL: https://jira.jboss.org/jira/browse/RF-8277
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-a4j-core
    Affects Versions: 3.3.3.BETA1
            Reporter: Mark Struberg


It seems the Filter currently tries to reformat the response in any case. But if you e.g. get a HTTP 304 response, this doesn't even have a content body (onyl headers) and wrinting to the response causes an Exception:
