我正在尝试加快我网站上的速度。YSlow 提醒我我的图像缺少过期标题。但是我如何在图像上应用这样的标题?

我的应用程序基于 zend 框架。图像也存储在文件夹中,我如何为它们设置过期标头?

如果您使用的是 apache,httpd.conf您可以执行以下操作:

LoadModule expires_module modules/mod_expires.so
ExpiresActive On
ExpiresDefault "access plus 300 seconds"
<Directory "/myProject/webResources">
    Options FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    Allow from all
    ExpiresByType image/gif "access plus 1 day"
    ExpiresByType image/jpg "access plus 1 day"
    ExpiresByType image/png "access plus 1 day"
    ExpiresByType application/x-shockwave-flash "access plus 1 day"
</Directory>

我昨天也遇到了同样的问题...

  1. 确保在生成图像的操作中设置了正确的标题。
  2. 您必须将带有“Content-Type”的 memorize_headers 添加到 frontendOptions 中,并且为了提高性能,还必须添加“Cache-Control”以及您要设置的任何标题...

因此,来自http://framework.zend.com/manual/en/zend.cache.frontends.html的 Zend_Cache_Frontend_Page 示例如下所示:

$frontendOptions = array(
   'lifetime' => 7200,
   'debug_header' => true, // for debugging
   'regexps' => array(
       // cache the whole IndexController
       '^/$' => array('cache' => true),

       // cache the whole IndexController
       '^/index/' => array('cache' => true),

       // we don't cache the ArticleController...
       '^/article/' => array('cache' => false),

       // ... but we cache the "view" action of this ArticleController
       '^/article/view/' => array(
           'cache' => true,

           // and we cache even there are some variables in $_POST
           'cache_with_post_variables' => true,

           // but the cache will be dependent on the $_POST array
           'make_id_with_post_variables' => true
       )
   ),
    'memorize_headers' => array(
        'Content-Type',
        'Cache-Control',
        'Expires',
        'Pragma',
   )
);

$backendOptions = array(
    'cache_dir' => '/tmp/'
);

// getting a Zend_Cache_Frontend_Page object
$cache = Zend_Cache::factory('Page',
                             'File',
                             $frontendOptions,
                             $backendOptions);

$cache->start();
