Currently the method render always returns a html string that can be a string that represents the correct result or a rendered error message. This change splits rendering and fetching of the HTML output. This simplifies the logic of the rendering and caching mechanism. Now the render method returns a boolean that indicates if the rendering was sucessful or not. Step 2/2 Warning: Errors in this change might affect caching logic and squid caches.
