Pipelining over a single persistent (tcp) connection?

[Garth P. <ga...@tw...>]

Is it possible to pipeline several queries over a single, persistent
tcp connection? We are using a provider for NAPTR record lookups that
is asking us to make requests over a single persistent connection. Is
it possible with the library? I can't figure out how you would modify
TCPClient to allow it, or how you would identify that a record was
associated with a particular query. Any ideas?
Thanks,
Garth
