    v3 v4  
    1212With the Django testserver this works fine, but in production (Apache + WSGI) it gives a lot of seemingly strange errors, such as unexpected 404s and (after including the package silk) unexpected 500 errors.

It gave me some pulled out grey hair, so I hope someone finds this anwers when the need is there.
