支持IPv4/IPv6套接字和Unix域套接字（UDS）。 IPv4/IPv6套接字可用于网络通信。 只有当外部应用程序与服务器在同一台机器上时，才能使用UDS。</p> <h4>Syntax</h4><p>IPv4 或 IPV6 address:port 或者 UDS://path</p> <h4>例子</h4><div class="ls-example">127.0.0.1:5434<br/> UDS://tmp/lshttpd/php.sock.</div><h4>提示</h4><p>[安全建议] 如果外部应用程序在同一台机器上运行，则首选UDS。如果必须使用IPv4|IPV6, 将IP地址设置为<span class="val">localhost</span>或<span class="val">127.0.0.1</span>，这样外部应用就无法从其他机器上访问。 [性能建议] Unix域套接字一般比IPv4套接字拥有更高的性能。</p> </article> </div> <div class="helpitem"><article class="ls-helpitem"><div><header id="maxConns"><h3>最大连接数<span

然而，真正的限制还取决于外部应用本身。如果外部的速度不够快，或者无法处理大量的并发请求，那么将这个值设置得更高也无济于事。</p> <h4>Syntax</h4><p>整数</p> <h4>提示</h4><p>[性能建议] 设置一个高值并不能直接变成高性能。设置为一个不会使外部应用程序过载的值，将提供最佳的性能/吞吐量。</p> </article> </div> <div
