    Hi Stefan,

     

    This is expected behaviour: "When the Cache Setting feature (referred to as RAM Cache in BIG-IP versions prior to 11.0.0) is enabled on a virtual server, all server-side requests generated by that virtual server will use the HTTP/1.0 protocol. This also applies to server-side requests derived from an HTTP/1.1 client-side request; all HTTP/1.1 requests are rewritten to HTTP/1.0. A Connection: Keepalive header will be added to allow persistent server connections."
