org.apache.shindig.gadgets.rewrite.ContentRewriterFeature
Parser for the "content-rewrite" feature. The supported params are include-urls,exclude-urls,include-tags. Default values are container specific. TODO: This really needs to be fixed, because it makes GadgetSpec mutable. It is *ONLY* needed by code in the rewrite package, and that code isn't even being used, and can't be used the way that they are currently written -- they require values from the gadget during construction, which are, of course, unavailable.

        rewriterFeatureFactory.createRewriteAllFeature(request.getCacheTtl());
