Python 3.14+http.serverterm

http.server.ThreadingHTTPSServer

servers

An HTTPS server that handles each request in its own thread: HTTPSServer plus ThreadingMixIn. Added in Python 3.14.

Syntax

ThreadingHTTPSServer(server_address, Handler, bind_and_activate=True, *, certfile, keyfile=None, password=None, alpn_protocols=None)

It is what python -m http.server --tls-cert cert.pem --tls-key key.pem runs. As with ThreadingHTTPServer, the threads are daemonic and die at exit, and shared data needs a lock. The TLS handshake happens in the request thread, so a slow client does not hold up the others, unlike the single-threaded HTTPSServer.

Examples

import socketserver
from http.server import ThreadingHTTPSServer, HTTPSServer
print(issubclass(ThreadingHTTPSServer, HTTPSServer))  # → True
print(issubclass(ThreadingHTTPSServer, socketserver.ThreadingMixIn))  # → True
print(ThreadingHTTPSServer.daemon_threads)  # → True
