La Fondazione "Apache Software" ha annunciato la disponibilitą della nuova versione 2.2.4 per quanto riguarda il demone HTTP che tutti noi conosciamo, Apache. La lista completa dei cambiamenti apportati č disponibile a questo indirizzo, mentre č possibile scaricare i sorgenti direttamente dalla sezione download del sito ufficiale.

Il ramo 2.2.x introduce una serie di nuove funzionalitą e migliorie, fra cui segnaliamo:

- Smart Filtering
mod_filter introduces dynamic configuration to the output filter chain. It enables filters to be conditionally inserted, based on any Request or Response header or environment variable, and dispenses with the more problematic dependencies and ordering problems in the 2.0 architecture.

- Improved Caching
mod_cache, mod_disk_cache, and mod_mem_cache have undergone a lot of changes, and are now considered production-quality. htcacheclean has been introduced to clean up mod_disk_cache setups.

- AJP Proxy
The new mod_proxy_ajp module adds support for the Apache JServ Protocol version 1.3 used by Apache Tomcat.

- Proxy Load Balancing
The new mod_proxy_balancer module provides load balancing services for mod_proxy.

- Graceful Shutdown support
The prefork, worker and event MPMs now allow httpd to be shutdown gracefully via the graceful-stop signal.
The GracefulShutdownTimeouthttpd will terminate regardless of the status of any requests being served.

- Large File Support
httpd is now built with support for files larger than 2GB on modern 32-bit Unix systems. Support for handling >2GB request bodies has also been added.

- Event MPM
The event MPM uses a seperate thread to handle Keep Alive requests and accepting connections. Keep Alive requests have traditionally required httpd to dedicate a worker to handle it. This dedicated worker could not be used again until the Keep Alive timeout was reached.

- refactored Authentication/Authorization
The bundled authentication and authorization modules have been refactored. The new mod_authn_alias module can greatly simplify certain authentication configurations. See module name changes, and the developer changes for more information about how these changes affects users and module writers.
