Hi!

I'd like to bring your attention to the question titled "Use HTTP/1.1
with SimpleHTTPRequestHandler" at

I find the doc slightly confusing. The SO code uses BaseHTTPServer. The doc says "Usually, this module isn’t used directly," On the other hand, SimpleHTTPServer only defines a request handler and not a server itself.

HTTP/1.1 with SimpleHTTPRequestHandler, loading a page that pulls in

What does 'hang' mean? Does the page get displayed? If so, server.serve_forever is supposes to 'hang'.

tiny test showing the problem. It's hard to believe that
SimpleHTTPServer doesn't handle such a simple task, does it? If I
checked correctly code is stuck in handle_one_request() method at
line 370 of server.py
(http://hg.python.org/cpython/file/d9893d13c628/Lib/http/server.py#l370)
but I can't see what's wrong. Any ideas?

The SO post says

class MyRequestHandler(SimpleHTTPRequestHandler):
    #protocol_version = "HTTP/1.0"   # works
    protocol_version = "HTTP/1.1"   # hangs

so this should be some sort of clue. The code says

569 # The version of the HTTP protocol we support.
570 # Set this to HTTP/1.1 to enable automatic keepalive
571 protocol_version = "HTTP/1.0"

The only substantive code I found using protocol_version (in the CPython default branch you linked to) is

300 if version_number >= (1, 1) and self.protocol_version >= "HTTP/1.1":
301 self.close_connection = 0

331 elif (conntype.lower() == 'keep-alive' and
332 self.protocol_version >= "HTTP/1.1"):
333 self.close_connection = 0
334 # Examine the headers and look for an Expect directive
335 expect = self.headers.get('Expect', "")
336 if (expect.lower() == "100-continue" and
337 self.protocol_version >= "HTTP/1.1" and
338 self.request_version >= "HTTP/1.1"):
339 if not self.handle_expect_100():
340 return False

I would re-test with the recently released 3.3.1 (and/or 2.7.4) to make sure nothing has changed
