36397	Server ignores 'Last-Modified' date (Debian#926074)	Christian Buhtz		"Hello,
First please take my apologize for writing such a broad ticket. But others, with more intel, I asked, didn't.

This is related to a (6 year old) Debian bug ticket: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926074
In short: The modified date is ignored by the server.

The Debian folks telling me that Django is somehow involved and there should go a bug ticket and fix.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926074#10

I can not tell because I lack of deeper understanding of the underlying technology.

I do have minimal working example demonstrating the problem with the Debian server.

{{{
>>> url = 'https://tracker.debian.org/pkg/feedparser/rss'

>>> a = fp.parse(url)
>>> import json
>>> print(json.dumps(a.headers, indent=4))

}
>>> a.modified
'Sat, 30 Mar 2019 13:06:51 GMT'
>>> b = fp.parse(url, modified=a.modified)
>>> len(a.entries)
30
>>> len(b.entries)
30
}}}

I would expect ""b.entries"" should be (near) 0.

I also can not tell wich version of Django is used by Debian.

Maybe you can give some comments in the Debian ticket?
