Varnish and language cookie

[Laurence Rowe]

I think this is your problem:

   11 TxHeader     b Cookie:
sessionid=fd0523a529b0a09861a235d1c2fdd7de; changed=true; open_tab=1;
rule_path=/general; django_language=fr;
   11 RxHeader     b Vary: Accept-Encoding
   11 RxHeader     b Vary: Accept-Language, Cookie

If your pages are the same for all users then you should remove Cookie
from the Vary.

I would also remove the custom vcl_hash and just set
req.http.Accept-Language to the value from the cookie, that way you
avoid caching multiple copies of any images etc.
