That is not what I was talking about when discussing using another 
protocol.

Requests passing through the chain may trigger events that take place outside
http.
          HTTP              HTTP                  HTTP
      UA  ---->  Org Proxy  ----> Regional Proxy  ---->  OS
                      |                |                  |
                      |                |                  |
                   Org Cache MEGA  Regional Cache MEGA   OS

In this way the protocol used to do entity replication from OS's to

say over the MBONE etc etc.
