Should mod_proxy_ajp or mod_jk be used for a production environment?

I've been searching over the past few days of whether I should use mod_proxy_ajp or mod_jk to connect apache httpd and tomcat. All the sites I find are a few years old and outdated.

So, which is best to use for a proper production environment? Is mod_proxy_ajp mature enough to entirely replace mod_jk, or is mod_jk still best if you can configure it correctly? Also, what's the difference in difficulty when configu开发者_JS百科ring each connector?

I've had mod_jk in production for about 4 years. It does what it's supposed to, and I don't have to think about it. I have no reason to change it.

For a new server I'd stick to what I already know works, unless there was a compelling reason not to.

The functionality isn't a complete overlap. I also remember reading somewhere that mod_jk is faster.
