Hi Shi, allow me to point at:
- http://blog.jboss.org/blog/mturk/2007/07/16/Comparing_mod_proxy_and_mod_jk.txt - http://anilsaldhana.blogspot.com/2006/04/modjk-versus-modproxy.html (and that's just the first two hits from Google using "apache mod_jk vs mod_proxy") So as a summary, your statement sounds too easy to reflect reality. If you are performance (=production?) oriented, there is still very good reasons to stay with mod_jk, despite the fact that it requires more configuration work. Further (just as a hint): Sites which are subject to PCI DSS scans, will be required to run at Apache 2.2.11 at least (unless they chose to go the WAF-way for web security). As this entire thread is addressing topics that I have repeatedly tried to "tweak" out of the community, I will take all this and club the info together for a HOWTO page in the wiki. Thanks all for the information provided. I knew there are folks out there running horizontally scaled OFBizes.
