Django & Docker & Traefik

Notes on errors

I migrated a django website with i18n enabled from using nginx to traefik and was getting the following error

  "msg": "vulcand/oxy/buffer: failed to read response, err: no data ready",

Reading this issue it turns out that when django redirected to the laguage version of the page the user was triying to access it didn't setup the Content-Length header in the response, this was because the locale middleware was defined before the common middleware.
