lighttpd 1.4.53 发布，高性能 Web 服务器

Lighttpd 1.4.53 已发布。Lighttpd 是一个开源 Web 服务器软件，旨在提供一个专门针对高性能网站，安全、快速、兼容性好并且灵活的 Web Server 环境。具有非常低的内存开销，CPU 占用率低，效能好，以及丰富的模块等特点。

重要更新

支持 TLS-ALPN-01，systemd socket activation，bug 修复

未来预期变化 (Q1 2019)

2019 年第一季度开始，lighttpd 默认对 HTTP 请求进行有限的 URL  规范化。

从 lighttpd 1.4.50 开始，这个 URL 规范就可用于 server.http-parseopts <https://redmine.lighttpd.net/projects/lighttpd/wiki/Server_http-parseoptsDetails>。除非已经对 lighttpd 配置做了明确设置，lighttpd 默认配置是 server.http-parseopts = (“url-normalize-unreserved” => “enable”, “url-path-2f-decode” => “enable”) 。默认开启 URL 规范会为 mod_redirect 和 mod_rewrite 带来更一致的行为，而这些行为会与（url 编码的） URL 请求更加匹配。然而，出于对一致性需要的默认情况下解码 %2F，对那些在 url-path 中解码 URLs、并且依赖 “/” 作为分隔符的用户，可能是个重大变化。对于这部分用户，可以在 lighttpd 配置中明确设置 “url-path-2f-decode” => “disable”。

https://redmine.lighttpd.net/projects/lighttpd/wiki/Server_http-parseoptsDetails

server.http-parseopts 推荐设置如下：

      server.http-parseopts = (
        "header-strict"            => "enable",
        "host-strict"              => "enable",
        "host-normalize"           => "enable",
        "url-normalize"            => "enable",
        "url-normalize-unreserved" => "enable",
        "url-normalize-required"   => "enable",
        "url-ctrls-reject"         => "enable",
        "url-path-2f-decode"       => "enable",
        "url-path-dotseg-remove"   => "enable",
        "url-query-20-plus"        => "enable"
      )
