get(), post(), etc. Each handler may define one or more of these methods to handle different HTTP actions. As described above, these methods will be called with arguments corresponding to the capturing groups groups of the routing rule that matched. Within a handler, call methods such as RequestHandler.render or RequestHandler.write to produce a response. render() loads a Template by name and renders it with JSON). Many methods in RequestHandler are designed to be overridden in subclasses and be used throughout the ap- plication. It is common to define a BaseHandler class that overrides methods such as write_error
