I'm no varnish or C expert, YMMV etc...
but I managed to get something like this working.
It's a VCL with embedded C that reads the "Accept-Language" header
and rewrites it (or writes into a different header, actually) the
result of some processing function.
Take a look at the examples here:
sample.vcl is the main VCL file, from which you embed the other one,
accept-language.vcl, which in turn contains the C function you want
I think `vcl_rewrite_accept_language()' is what you need.
Then you're only missing the upper->lower case bit.
