Can't you add a custom header on your req object in vcl_recv that tells if it's a restart or not ?
<div><br>
</div>
<div>Then you check this header to know if you must create the hit_for_pass object. </div>

<div class="PlainText">ok i have tried this solution, and it seems to work but i still have somes problems<br>
<br>
let me explain, in v3 my restart rule is the following one:<br>
<br>
if(beresp.status == 404 && req.restarts == 0) {<br>
return(restart);<br>
}<br>
<br>
and i also have a rule to hit_for_pass object that is not a status 200:<br>
<br>
if (beresp.status != 200 && beresp.status != 206 && beresp.status != 301) {<br>
return (hit_for_pass);<br>
}<br>
<br>
so now in v4 if i restart in vcl_deliver, i have an hit_for_pass object inserted in the cache (because status 404), and it is not good.<br>
<br>
so i thought to add a special rule before the hit_for_pass, like this one:<br>
<br>
if(beresp.status == 404 && req.restarts == 0) {<br>
return (deliver);<br>
}<br>
<br>
but in v4 i can't use req.restarts in vcl_backend_response... ! :(<br>
