Keepalives generate different versions of HTTP

[RHLloydBGF]

The following extract from the config of a CSS11051 shows two services monitored by a HTTP keepalive. A SNOOP on the servers show that the first keepalive is generating HTTP version 1.0 requests and the second is generating HTTP version 1.1 requests. We have a problem that the first keepalive does not always work and would like to rule this out. Does anyone know if it is possible to control the HTTP version and force it to use HTTP version 1.1? Thanks.

Should get you started

The CSS will always attempt a http 1.1 keepalive first and then if it can negotiate that it will attempt 1.0

The only control you have on the keepalive is actually opposite of what you would like to do.

In the keepalive you can force the non-persistent connections.

keepalive type http non-persistent <-- Don't attempt persistent connections
