Perhaps but this cookies sets not by me (maybe JS ads widget or etc). And I
can't fix it. I can't auth users
New submission from Yuriy Zhuravlev:
After I migrated my site to Python 3.5 from 3.4 many users of my site have not
been able to login. After small research I found out that users cookies there
was a key without value and new Python get empty SimpleCookie result.
Example for Python 3.5.2
