It's now time to refactor and redesign it with Apache 2.x (APR/AP) in mind to follow Apache 2.x admins habbits and try to make something simpler.
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.
Or maybe just a channel for passing config data ( but leave request passing to mod_proxy ) ?
I.e. the only thing that will remain in mod_ajp will be the autoconf and monitoring.
- 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
Can we simplify this ?
Let's drop the word "worker" too :-)
The request is passed to a servlet container that may consist of one or multiple instances.
Agreed, remove the old terms.
The proposal about mod_proxy + proxy_ajp could be something fine isn't it.
And proxy_ajp could map to a dynamically updated ajp resource ?
