我有一个非常简单的 PHP 脚本来测试我的 mod_cache 设置。但是,它不起作用——我可以从等待页面加载的 5 秒延迟以及打印的日期看出这一点。
<?php
ob_start();
header('Last-Modified: '.gmdate('D, d M Y H:i:s', filemtime(__FILE__)).' GMT', true, 200);
header('Cache-Control: max-age=31536000, public',true);
header('Pragma: Public',true);
header('Expires: ' . gmdate('D, d M Y H:i:s', strtotime('now + 10 years')) . ' GMT',true);
header("Vary: Accept-Encoding");
header("Content-Type: {$mime}",true);
sleep(5);
echo "test: ".date('n/d/y g:i:s A');
header('Content-Length: '.ob_get_length());
ob_end_flush();
此脚本与 mod_php 配合使用效果很好。mod_fastcgi 内容无法缓存吗?我是否需要更改标头才能使内容可缓存?欢迎提出建议。
编辑:添加相关的 apache 配置:
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
LoadModule fastcgi_module modules/mod_fastcgi.so
FastCgiConfig -idle-timeout 20 -maxClassProcesses 1
AddHandler php5-fcgi .php
Action php5-fcgi /cgi-bin/php.fcgi
<Location "/cgi-bin/php.fcgi">
Options ExecCGI
SetHandler fastcgi-script

错误 48364Apache 的 bugzilla 最终可能会对此有所帮助,尽管到目前为止还没有。
