Comment (by Anders Kaseorg):
A redirect response is allowed to have a body, so in order for keep-alive
to work, the HTTP server must send either `Content-Length` or `Transfer-
Encoding: chunked`. It’s less clear that the WSGI application should be
responsible for sending it explicitly. I would have expected uWSGI to
automatically add `Transfer-Encoding` if `Content-Length` is not provided,
but evidently it doesn’t.
This is easy to reproduce without Django, so I don’t think we should feel
obligated to avoid fixing this just to have a reproduction recipe.
{{{
#!python3
def application(environ, start_response):
body = b"Hello, world!"
start_response(
"200 OK",
[
# ("Content-Length", str(len(body))), # uncomment to fix
],
)
yield body
}}}
