Persistence HTTP connection

I try to connect my soap-client to a soap-server that is working with
Persistence HTTP connections:
The Server-API works with logical sessions. If the HTTP Response is done,
my SOAP::Lite  client closes the TCP/IP connection to the server. In this
case, for the server the logical session is also closed an I lost the
logical session handle (API-Stuff).
With .NET it is possible to handle persistence HTTP connections.

Question: It is possible to handle more then one SOAP-Requests for one HTTP
(TCP/IP) connection without closing the socket for each Request ?
