Question

我在调度程序中有以下配置文件用于缓存。我可以缓存js，css但不能缓存JPEG / PNG。如果我在某个地方出错，请建议我？我还需要缓存图像

ExpiresActive On
ExpiresByType text/css "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 month"
ExpiresDefault "access plus 2 days"

这是dispatcher.any文件配置

# Hello Publish Farm
/publishfarm_hello
{
# client headers which should be passed through to the render instances
# (feature supported since dispatcher build 2.6.3.5222)
/clientheaders

  # caches also authorized data

  }
  # the invalidate section defines those pages which are 'invalidated' after

根据AEM documentation，您可以使用＆＃34; / rules＆＃34;来控制基于适当文档路径缓存的文档。属性。请检查/ rules属性

下是否有类似于以下的配置

/rules
    {
    # initial blanket deny
    /0000
      {
      /glob "*"
      /type "deny"
      }
    # low-change static assets
    /0001
      {
      /glob "*.png"
      /type "allow"
      }
    /0002
      {
      /glob "*.gif"
      /type "allow"
      }
    /0003
      {
      /glob "*.jpg"
      /type "allow"
      }
    /0004
      {
      /glob "*.jpeg"
      /type "allow"
      }

如果根据adobe link，那么在某些情况下调度员永远不会缓存文档。请查看您的案例是否与这些情况相符

Answer 2

您是否在调度程序缓存中看到图像？基本上，您共享的配置是针对mod_expire的，与调度程序无关。据我所知，mod_expire不会应用标头，除非资源是从apache提供的（不是从AEM蒸来的）。

AEM中没有发生缓存图像
