New submission from Oliver Urs Lenz <oliver.urs.l...@gmail.com>:
SimpleHTTPRequestHandler.send_head() has this bit:
if os.path.isdir(path):
parts = urllib.parse.urlsplit(self.path)
if not parts.path.endswith('/'):
# redirect browser - doing basically what apache does
self.send_response(HTTPStatus.MOVED_PERMANENTLY)
https://github.com/python/cpython/blob/521995205a2cb6b504fe0e39af22a81f785350a3/Lib/http/server.py#L676
I think there are two issues here:
1) why should the server return a redirect code here, and not (in the code that
immediately follows) when it serves an index file?
2) code 301 (permanent redirect) is really unforgiving, browsers like Firefox
and Chrome will permanently cache the redirect, making it essentially
impossible to undo if you do not control the client, and not trivial even if
you do. This will probably not change on the browser-side, general opinion
seems to be that limited caching should either be specified in the response
header or that a different redirect code should be sent back.
https://lists.w3.org/Archives/Public/ietf-http-wg/2017OctDec/thread.html#msg363
Therefore I would like to propose that preferably,
- no redirect code be sent back, or else that
- a different redirect code be sent back, or else that
- no-caching or a time limit be added to the header
(This may require that send_head check for index files instead)
