By the way, I don't think you can redefine VCL functions multiple
times as you do in this configuration. It will consider only the first
definition.

I do this very frequently (but with Varnish 3.0.2). The idea is the
same, but I use hash_data to add the custom string "deDE". Here, the
only thing you really need is this configuration. With this, varnish
must be generating a different cache entry for this request with the
cookie.

To know exactly what is happening, you must use 'varnishlog' command
and look at what varnish is doing, if it's adding the custom hash, and
so on.
