Another way to do this is to :

o send the squid that you want to push the object to an ICP_OP_QUERY
o if it returns HIT then it already has it !
o if it returns MISS then do a HTTP GET request to it.
o the squid then sends out ICP_OP_QUERY for that object, you then respond
   really fast with a HIT and the squid comes and gets it
o you have to bit bucket the same object it sends back though.
