Thanks for henrik's advice, I am running a file server that often
requested by multi-thread download tools, if squid can prefetch and
cache files, It will make my back-end server do less work.

I find some email lists talking about this matter here:
http://www1.uk.squid-cache.org/mail-archive/squid-users/200404/0962.html
it's replied by henrik too, but I am still not understand How squid
think about "abort" ? squid treat all the Range request as "abort" ?
What about the browser window  is closed by some one while requesting
a file?
