HTTP 1.1 Pipling Requests
Hi,
i have read the rfc 2616 and have a understanding question to you, if
you can help me ;-))
---
8.1.2.2 Pipelining
A client that supports persistent connections MAY "pipeline" its
requests (i.e., send multiple requests without waiting for each
response). A server MUST send its responses to those requests in the
same order that the requests were received.
Clients which assume persistent connections and pipeline immediately
after connection establishment SHOULD be prepared to retry their
connection if the first pipelined attempt fails. If a client does
such a retry, it MUST NOT pipeline before it knows the connection is
persistent. Clients MUST also be prepared to resend their requests if
the server closes the connection before sending all of the
corresponding responses.
Clients SHOULD NOT pipeline requests using non-idempotent methods or
non-idempotent sequences of methods (see section 9.1.2). Otherwise, a
premature termination of the transport connection could lead to
indeterminate results. A client wishing to send a non-idempotent
request SHOULD wait to send that request until it has received the
response status for the previous request.

As i understand this part a HTTP-Header parser should parse for a
'empty-line' and look after the 'empty-line' if a 'idempotent method' is
in the next line. If one of the 'idempotent method' is there i can
assume a pipline equest.
How do you handle pipline requests in the apache?
