Only idempotent requests can be pipelined, such as GET and HEAD requests. POST and PUT requests should not be pipelined. We also should not pipeline requests on a new connection, since it has not yet been determined if the origin server (or proxy) supports HTTP/1.1. Hence, pipelining can only be done when reusing an existing keep-alive connection.
