Apache HTTP Server 2.2.17 版本发布，最流行的HTTP服务器软件之一。快速、可靠、可通过简单的API扩展，Perl/Python解释器可被编译到服务器中，完全免费，完全源代码开放。 如果你需要创建一个每天有数百万人访问的Web服务器，Apache可能是最佳选择。
Changes with Apache 2.4.27
*) COMPATIBILITY: mod_lua: Remove the undocumented exported ‘apr_table’
global variable when using Lua 5.2 or later. This was exported as a side effect from luaL_register, which is no longer supported as of Lua 5.2 which deprecates pollution of the global namespace.
*) COMPATIBILITY: mod_http2: Disable and give warning when using Prefork.
The server will continue to run, but HTTP/2 will no longer be negotiated.
*) COMPATIBILITY: mod_proxy_fcgi: Revert to 2.4.20 FCGI behavior for the default ProxyFCGIBackendType, fixing a regression with PHP-FPM. PR 61202.
*) mod_lua: Improve compatibility with Lua 5.1, 5.2 and 5.3.
PR58188, PR60831, PR61245.
*) mod_http2: Simplify ready queue, less memory and better performance. Update
mod_http2 version to 1.10.7.
*) Allow single-char field names inadvertently disallowed in 2.4.25.
PR 61220.
*) htpasswd / htdigest: Do not apply the strict permissions of the temporary
passwd file to a possibly existing passwd file. PR 61240.
*) core: Avoid duplicate HEAD in Allow header.
This is a regression in 2.4.24 (unreleased), 2.4.25 and 2.4.26.
PR 61207.
