dk.brics.jwig.server.cache.Cache
The cache is responsible for caching responses, generated by JWIG and sent to the client.

            response.setHeader("Connection", "close");
            response.setContentLength(0);
            response.getOutputStream().close();
            return true;
          }
          Cache cache = ThreadContext.getCache();
          StringBuilder updates = new StringBuilder();
          for (int i = 0; i < fragmentnames.length; i++) {
            String name = fragmentnames[i];
            String etag = etags[i];
            Response p = cache.get(name);
            if (p == null || !etag.equals("\"" + p.getETag() + "\""))
              updates.append(name).append(';');
          }
          if (updates.length() > 0) {
            String u = updates.toString();
