ch.entwine.weblounge.common.impl.request.CacheTagSet
A CacheTagSet holds a set of cache tags and specifies either a unique key used in a cache handle or a matcher when it comes to selecting elements from the cache.
The set allows multiple tags with the same key, but only one tag with a key-value pair.

      if (!noCache && request.getVersion() == Resource.LIVE) {
        long expirationTime = action.getCacheExpirationTime();
        long revalidationTime = action.getClientRevalidationTime();


        // Create the set of tags that identify the request output
        CacheTagSet cacheTags = createCacheTags(request, action);


        // Check if the page is already part of the cache
        if (response.startResponse(cacheTags.getTags(), expirationTime, revalidationTime)) {
          logger.debug("Action answered request for {} from cache", request.getUrl());
          return true;
        }


        processingMode = Mode.Cached;
