The answer you are looking for is true for almost any / all Server Daemons that are not multi-threaded. Imagine every "Request" and "Response" as a separate task that is done independently of all the others, and bound together via some type of identification tags or pointers in memory that are then compared to match up to each other. If Squid were to send a single GET across a connection, it will wait for the data to be received in that connection before reusing it, if at all. Otherwise, just like any other daemon, the connection is dropped, and a new connection is opened for more data. It's all done on a "case-by-case" basis. --------------------------------------------- Chad E.

How does it work for a single client that has pipelining implemented. If two GET requests are sent to the server and if hypothetically ( a poorly implemented) server responds only to the second GET, how does squid (and the client) map the response to the second request ? If squid happens to cache that response, any subsequent client requesting that resource could get the wrong page served. This is possible right ? Essentially, squid continues to depend on the "sequence" of the responses from the origin server and has no way of matching responses to particular request (even from the same client).
