Pragma Directives:

  • Clients MUST add a "No-cache" pragma directive as specified in [RFC2616] section 14.32. Inbound proxies MUST ignore this directive.

  • If the higher-layer protocol or application specified a connectiontimeout, a client MUST add a pragma directive of the form "Pragma:MinConnTimeout=T", where T is a decimal string representation of the minimum connection time-out, in seconds, to be used for this IN channel. The time-out MUST be in the inclusive range of 120 to 14,400 seconds.
