[squid-users] Fwd: in-transit objects and more new requests for them

greeting every one

I made a request to a big file with url lets say url.ca/big_file.tgz
from one client machine through squid and while it was pending-store
after a little while made another request from another client machine
to the same file. here is the output of

squidclient -p 1210 mgr:vm_objects 2>&1 | grep -i -B 6 -A 5 "big_file.tgz"

as you can see, squid creates two entries for each of them. then I
tested the server of url.ca and figured out squid creates two separate
download for each requests, while they are exactly the same. how to
make squid to use the pending in-transit object for every requests
instead of create a new download for them.
I know it might be a security risk, but it might be very usefull for
special cases that security does not matter.
