[squid-users] Sudden but sustained high bandwidth usage

This way it won't cache any "range" downloads as "range_offset_limit 0" 
is the default option and it will make squid only download what the 
client requested.

 From squid-cache.org: "A size of 0 causes Squid to never fetch more 
than the client requested. (default)"

What I'm trying to accomplish here, and have done while using AUFS, is 
to make squid CACHE/STORE RANGED REQUESTS for windowsupdate.com, instead 
of its default action of aborting.

How can I monitor whats the reason of all the "TCP_SWAPFAIL_MISS" on 
range downloads like these:
