May I direct your attention to the second sentence of my post?
It fixes an issue in the Python built-in HTTP server that causes it to hang under concurrent connections.
First, run the built-in Python web server:
[term1]$ python -m SimpleHTTPServer 8080
Then connect to it with a client that doesn't immediately send a request, such as `netcat`. This simulates the behavior of modern browsers, which seem to set up a pool of pre-established connections.
[term2]$ nc localhost 8080
Now try to get a page from the server via Curl (or wget, etc). It will hang after sending the request, because the server's single thread is trying to serve the idle connection.
[term3]$ curl -v http://127.0.0.1:8080
* Trying 127.0.0.1:8080...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET / HTTP/1.1
> Host: 127.0.0.1:8080
> User-Agent: curl/7.68.0
> Accept: */*
>
In real life, the behavior I saw was that I'd try to connect to the server with Chrome and it would hang after the pages had partially loaded.
I think this is a problem that's long been fixed; I tested your command and it seems to work as expected for me in Python 3.10 anyway. And I've been using the "python -mhttp.server" frequently for years, and never experienced any of these problems.
