No. AJP14 was an experiment to extend AJP13 - but we agreed that keeping Ajp13 stable and frozen and stable ( and remaining compatible with the whole range of tomcats ) is better than whatever improvements we could gain. And I strongly believe that in the future we'll either stick with ajp13, or implement a subset of XDR or CDR - i.e. a standard marshalling ( and an even smaller subset of the rpc semantics ). To avoid confusion, we should stop discussing about Ajp14 - and stop using the same term for protocol and API. There is one wire ( binary ) protocol, ajp13. PROPOSAL: let's use 'jk1 API' to refer to the set of methods/callbacks used in jk1 - that's the base API that is supported in all tomcat versions ( starting with 3.2 ). The only reference to ajp14 should point that there is no ajp14. Ajp13 was designed from start as a RPC-like protocol ( with minimal overhead, etc ), and we don't have any use case where ajp13 wouldn't work. The only limitation is that it support only 255 methods ( unless we use an expansion ), since it has a byte as method code ( to facilitate table-based dispatching ).
