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

Hey mohamad,

The key is meant for searching and finding something in the DB.
as you see that there are two keys it might be a HEAD and GET requests
or another thing.

Squid has a testing branch for a function called "collapsed forwarding"
which you can try and might find that it is what you are looking for.

What version of squid are you using?
