Running CWS in CTS 2.2

We are running CWS in CTS 2.2. In the TCPIPSERVICE definition we have defined SOCKETCLOSE(0). We will test persistent...

connection ex SOCKETCLOSE(20). The manual CICS Internet Guide 2.2 says: "CICS supports only the HTTP 1.0 Keep-Alive implementation of the persistent connections, not the HTTP 1.1 implementation."

Whether you run HTTP 1.0 or 1.1 is depending on what's defined in the client. Standard for IE 5.5 or 6.0 is HTTP 1.1. One difference between HTTP 1.0 and 1.1 is that in 1.0 the server disconnects from the client after completing the request and in 1.1 the server by default keeps the connection open. Does this mean that the SOCKETCLOSE definition for HTTP 1.1 is of no use? Or have I misunderstood?


I'm sorry to say that for CTS 2.2 your understanding is correct. We only obey the HTTP 1.0 protocol. That is what should be negotiated from the browser as it looks like the browser is assuming HTTP 1.1 then the TCPIPSERVICE definition will have the effect you observe. Sorry.
