缓存配置后，一些图像在 Magneto 上的缓存时间仍然不同

我在 nginx 上运行 magneto，并且配置了一年的图像缓存，仍然在 gtmetrix 中缓存一些我得到的图像（5 分钟）

我最好的猜测是你还没有将 headers_more 编译到 Nginx 中。要确认你是否已将其添加到你的图像位置块中

add_header XYZ "TESTING";

发布“curl -i”的输出，或者您可以使用 Firefox 和“Live HTTP Headers”插件查看标头。另外，删除“pragma”，它已经过时且没有必要。基本上，复制下面的我的块，至少复制您需要的部分。

如果你需要有关如何使用 headers_mode 构建 Nginx 的说明，请参阅我的教程这里。

作为参考，这是我自己的位置博客，它做了类似的事情

# Cache images on the client. Don't log errors or access. Block hotlinking.
location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {
  log_not_found off; access_log off;

  valid_referers none blocked server_names ~($host) ~(googleusercontent|google|bing|yahoo);
  if ($invalid_referer) {
    rewrite (.*) /stop-stealing-images.png redirect;
    # drop the 'redirect' flag for redirect without URL change (internal rewrite)
  }

  # Set up caching - 8 days for static resources. Remove the old unnecessary Pragma and hide the server version
  more_clear_headers "Cache-Control";
  add_header Cache-Control "public, max-age=691200, s-maxage=691200";
  more_clear_headers Server; more_clear_headers "Pragma"; more_clear_headers "Expires";

  # add_header Z_LOCATION "wpmu STATIC RESOURCES REGEX"; add_header URI $uri; # Nginx Debugging
}
