سلام
آپاچی ورژن 2.4.4 منتظر شد و در easyapache نیز قرار گرفته است.منتهی با توجه به تست هایی که بر روی چندین سرو راشتراکی و اختصاصی انجام دادم مناسب برای سیستم های اشتراکی نیست.باتوجه به عدم پشتیبانی از یکسری ماژول ها و فانکشن های قدیمی که برای مدیریت بهتر ترافیک کانکشن ها و ... بر روی اپاچی 2.2 و 2.0 ارایه شده بود فعلا از بروزرسانی سیستم های اشتراکی به این ورژن خودداری کنید.
به طور مثال از بارزترین موارد در این ورژن، حذف mod_gzip و جایگرینی mod_deflate هست که باتوجه به عملکرد بهتر mod_deflate در کاهش حجم و زیپ، تغییر محسوسی است
در زیر تغییرات فنی انجام شده در این ورژن شرح داده شده است:

Content-Length. [Micha Lenk <micha lenk info>]
