Yes, that's exactly what I want.

So I just add this line to the vcl_recv function:

 sub vcl_recv {
        if (req.http.host ~ "^xxxx") {
                set req.backend = xxxx;
                *if (req.url ~ "^/iso/") {*
*                        return(pass);*
*                }*

The time out is always activated ?!
The only difference is what, now, wget can use the "206 Partial content"
option, but firefox can't :(

I am sure what I fail on something, because with the pass action, no time
must be send to the client anymore.
