- The Event MPM is no longer experimental and is fully supported – this gives greater performance ala nginx.
- Conditionals in config – so you can have for example, a generalized config across multiple hosts with slightly different requirements. Similarly, you can have config file variables.
- mod_remoteip – allows you to easily get the “true” client IP when behind load balancers.
- mod_sed – rewrite input and output.
- mod_auth_form – HTML login forms for basic authentication. Much easier for the end user than the unfriendly pop-up dialogue.
- mod_ratelimit – very basic DOS protection.
- mod_ssl supports sharing SSL session details across servers via memcached for performance.
- mod_lua (experimental) allows hooks into Apache to be written in Lua!
