Hi, can someone explain me how SQUID handles intercache communication especially how does it forward HTTP request to parent proxy. SQUID is not using any caching protocol. cache_peer configuration: cache_peer A.B.C.D parent 8080 0 no-query no-digest no-netdb-exchange round-robin proxy-only Is it using one TCP connection with parent proxy or is it opens separate connection for different HTTP requests? What about pipelined connections to parent proxy? Thanks in advance, Dalibor
