We came on httpd-dev for advice from experts, and may be an
extended mod_proxy could be the solution. But we also want to keep
the AJP/1.3 and AJP/1.4 protocols since it works well and so a pure
HTTP proxy is only part of the game.


I think any module that speaks ajp/1.X should be called mod_ajp, keeps things simple and clean.

We agree and I wonder if a mod_ajp could be used in conjunction with mod_proxy ? A sort of alternative way to route requests to tomcat.

- Could mod_proxy be open to support AJP/1.x as tomcat connections ?


I don't think mod_proxy should support ajp, rather a dedicated ajp module should.

We agree.

But I'm still not convinced a separate protocol is needed when HTTP exists and is supported already.

The "httpd serves the static content" feature can be implemented through extending ProxyPass to support regular expressions, for example:

ProxyPass /myWebapp/*.jsp http://tomcat/myWebapp/

I'm not sure if persistent connections over and above HTTP/1.1 keepalives is that useful.

Well let see my suggestion :


ProxyPass /myWebapp/*.jsp ajp://myajpworker/

myajpworker is not a machine but a virtual resource which could be :

- a physical Tomcat using its AJP/1.3 connector

- a cluster of physical Tomcats using their AJP/1.3 connector

And via AJP/1.4 we could make Apache 2 learn about cluster updates
in real-time.

Could we have this kind of Virtual Forward service used with mod_proxy ?
