sticky module was -> RE: AJP

[姚伟斌]

Hey,

That's the opensource module. It may not as official as the nginx native
module. It all depends the module author's  ability and time. You should
use it after you test it completely. It's free.

If you want the official support, you can contact with nginx company:
http://nginx.com/support.html
