is there a default vlc for varnish 5

[Admin Beckspaced]

hello varnish users,

I'm using varnish 5 and I'm actually quite new to varnish, so i 
apologize in advance, if I'm asking 'stupid' questions ;)

I'm currently thinking about the following:

sub vcl_hash {

   # If the client supports compression, keep that in a different cache
   if (req.http.Accept-Encoding) {

     hash_data(req.http.Accept-Encoding);

   }

}

do I need to do this? or is there some default vlc_hash by varnish, 
which automatically does those things by itself?
and if so, where can i find the default varnish vlc? github? link to the 
documentation?

thanks & greetings
becki
