No. No pipelining is done between two caches. Only one request at a time
is sent on a persistent cache-cache or cache-server connection. The
reason to this is that to many things can go wrong when pipelining
requests, and HTTP discourages pipelining of requests on a shared HTTP
connection.

Squid supports pipelining of client requests, with a limit of four
outstanding request. Pipelined requests are however not well tested and
there may be some bugs left, especially on uncacheable replies or
replies which forces Squid to close the connection (no known
content-length).
