The Mod_Proxy Cookbook
summary
Practical recipes for mod_proxy and mod_proxy_balancer on Apache HTTPD 2.4: how to enable HTTP/2 proxying, use active health probes (built-in backend probing and HTTP response matching), configure connection pooling, sticky sessions via mod_headers cookie injection, UNIX domain socket backends, and the balancer manager with persistent state. Examples include a Node.js SSL offload case claiming ~6k→38k req/s gain through UDS, plus exact config fragments and health-check templates.
