Thank you for this, my conf applied already to this, but maybe you should tell about that in your docs too. (:

Unbelievable! :D Ive seen "insert id" header in ngx_drizzle, but hadnt looked further at inserts with rds_json (damn stupid me, i should write an article about that).

I have a php-fpm install for exactly 3 apps which are our webmail/cms/board, because php-users are not aware of their risks ive disabled it apart from that. NCARS rulez, but im replacing it already -> xmpp (psyc) + web frontend.

I used techniques like MEF and such in .Net, but imho its desktop-only.. One can do amazing things with it, also without using client-side runtime, but if you're not bound to that platform, why would you do?

Its good to have varnish, ha and/or simple nginx in front of such servers/frameworks, but now nginx+lua is enough, its so tiny and fast..
