Varnish redirect based on browser language settings

Question

I am using varnish 4 in front of apache. I need requests made to deutsh.de coming from headers with the preferred language es or ca (unless it also has de or en) to be redirected to spanish.es. Could somebody provide me with the appropriate syntax? Thank you

Answer 1

So I managed to put together something in the file used to start varnish:

sub vcl_recv {
       if((req.http.Accept-Language !~ "de" || req.http.Accept-Language !~ "en")  && (req.http.Accept-Language ~ "es" ||  req.http.Accept-Language ~ "ca" ||  req.http.Accept-Language ~ "eu"))
         {
        return(synth(301,"Moved Permanently"));
         }
}

sub vcl_synth {
      if(req.http.Accept-Language ~ "es" ||  req.http.Accept-Language ~ "ca" ||  req.http.Accept-Language ~ "eu")
         {
        set resp.http.Location = "http://spanish.es";
        return (deliver);
}
}

...This appears to work
