Re: HTTP Working Group 'issues' list

    I don't believe you are allowed to send a second request on a
    persistent connection before you get a complete reply.

It is somewhat more complex than this.  Our subgroup's consensus is

    Persistent connections are meant in part to support pipelining
    of requests and responses.  However, a client MUST NOT pipeline
    its requests until the server has indicated that it will create
    a persistent connection.  We believe that otherwise, certain
    servers or proxies could become confused.  We will allow a client
    to remember that a given server has recently allowed persistent
    connections (say, within the past 1 day).

Given the last sentence, most of the time the client probably
WILL be sending multiple requests without intervening replies.
