in fact I did

if (req.url ~ "\.pdf$|\.png$|\.gif$|\.jpg$|\.mp3$|\.svf$")  {
     

    if (req.http.Authenticate || req.http.Cookie ~ "__ac=") {
                       pipe;
    }
    lookup;

}

I suppose pipe also terminates vcl_recv() 
I tried also
if (req.url ~ "\.pdf$|\.png$|\.gif$|\.jpg$|\.mp3$|\.svf$" && !(req.http.Cookie ~ "__ac=") )  {
         lookup;
     }
it seems slow

Any workaround to accomplish partial cache with cookies ?

thanks again
