It is not based on WSGI [https://wsgi.readthedocs.io/en/latest/], and it is typically run guide for more on Tornado’s approach to asynchronous programming. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written written to use Tornado’s own interfaces (such as tornado.web) directly instead of using WSGI. In general, Tornado code is not thread-safe. The only method in Tornado that is safe to call from other threads
