I'm not sure what you mean by "HTTP1.0 session".  Are you talking about the
TCP/IP connection, or about sessions that an application server may create?

The server closes its end of a true HTTP 1.0 connection when it is done
sending the response, and the client closes its end when it is done reading
the response.  Many clients and servers that send requests and responses
claiming to be HTTP/1.0 also support keep-alive, which I believe was
originally defined by Netscape.  This evolved into the persistent connection
feature of HTTP/1.1.  A client supporting keep-alive includes the header

    Connection: Keep-Alive

A server that does not support keep-alive does not include a Connection
header.  A server with keep-alive disabled will return

    Connection: close

In either of these cases, the client will close its connection when the
response is read.  If the server supports keep-alive, it sends

    Connection: Keep-Alive [...]
    Keep-Alive: [...]

where [...] is optional stuff to tell the client how long the connection
will remain open without any data transmission.  This timeout is often
configurable on the server, but is usually something like 10 or 15 seconds.
It is almost never longer on even moderately busy servers.

Apache SOAP does not support persistent connections.

Apache SOAP works with IIS, but IIS alone is not enough.  Apache SOAP
requires a J2EE container (although it only needs Web container features,
not EJB), which is not part of IIS.  There are a number of J2EE containers
that work with IIS.  Of course, there are also products like Tomcat or Resin
that provide both a Web server and J2EE container.

Hi,
Does anyone know how long HTTP1.0 session stays alive? I do know
HTTP does expires after a period of time. How long is that? Can I set
it?

Also does apache SOAP work with IIS?

Thanks a lot,

Hongda
