The most widely-used web server software in the world, Apache, has been updated to 2.2.0, announced on their website. Version 2.2.0 is of course free and has a very large list of improvements and fixes, much larger than other 2.x releases. Some of the changes include improvements to caching functions, better proxy and filtering support and a lift on the very old 2GB file limit (which has plagued some people for years). You can find a full update list at Apache's site. As with previous versions of Apache it is free software and is available for multiple platforms. Including all versions of Windows, Netware, Unix and Linux, BSD and more. Apache is used on more than 70% of the world's webservers.
