If it first tries to fetch the page from the net that means you have
to wait for the DNS timeout on every page when you don't have
net. IMHO that's close to unusable.

Something like

 if ping -c1 $IP_ADRESS_OF_YOUR_NAMESERVER; then
   wwwoffle -online
   wwwoffle -fetch
 else
   wwwoffle -offline
 fi

would do the job. And wwwoffle will fetch any page you requested
offline as soon as you have net.
