Hi,<br><br>Is prefetch by default enabled in varnish ? I have following in VCL . A value of -30 seconds would mean that the object would be checked 30 seconds before its expiry time is reached to see if its modified on backend ?<br>
<br><br>sub vcl_fetch {<br> set obj.grace = 30s;<br> if (!obj.cacheable) {<br> pass;<br> }<br> if (obj.http.Set-Cookie) {<br> pass;<br> }<br> set obj.prefetch = -30s;<br> deliver;<br>}<br>
<br><br>I see following from varnishlog . What doe that mean ?<br><br>26 VCL_info c XID 3904284923: obj.prefetch (-30) less than ttl (-1.26414e+09), ignored.<br><br>0 VCL_call - prefetch<br>0 ExpPick - 3903448954 prefetch<br>
<br><br><br>Thank you.<br><br>-Paras<br>
