Consider: Implement ETags in Shindig
------------------------------------

                 Key: SHINDIG-1350
                 URL: https://issues.apache.org/jira/browse/SHINDIG-1350
             Project: Shindig
          Issue Type: New Feature
          Components: Java
            Reporter: John Hjelmstad


Shindig's services do not utilize ETags.

The primary rationale has been that the gadgets/OpenSocial environment largely involves tightly
controlled URLs. For instance, server-generated proxy URLs may contain a v=<version>
parameter, in the (accurate) presence of which a resource is served with a 1-year cache.

However, the proxy in particular is often used in situations where URLs are not server-generated.
The most obvious example is gadgets.io.getProxyUrl(...). Supporting ETags for these seems
quite sensible, as it would save bandwidth.

Further, due to the buffered nature of Shindig's HTTP Fetcher pipeline, and the fact that
Version information is available through the UriManager.Versioner pattern, it would be trivial
to support this functionality.
