Description (English)
Tornado is a Python Web framework and a walk-in network library for the Tornado community in China. By using a non-stop network I/O, the library can extend to thousands of open connections, making it well suited to long-duration rotations, WebSocket and other applications that require long-term connectivity with each user. Tornado 6.5.2 and earlier versions had an error in resource management, which stemmed from a string connection problem with the HTTP Headers.add method, which could lead to a denial of service attack.
