在AEM中沒有緩存圖像

Question

我有下面的配置文件用於在調度程序中進行緩存。我能夠緩存js，css而不是JPEG/PNG。請告訴我，如果我在某個地方出錯了？我需要緩存圖像以及

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" 

這是dispatcher.any文件中的配置

# Hello Publish Farm 
/publishfarm_hello

按照AEM documentation，您可以控制哪些文件會被緩存使用「/法規爲基礎的適當的文件路徑「財產。 請檢查您是否有類似的配置，以低於下/規則屬性

/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" 
     } 

如果它的存在，因爲按照adobe link，也有給予一定的情況下，該調度員從不緩存文件。請參閱您的案例是否符合上述任何一種情況

Answer 2

您是否在調度程序緩存中看到圖像？基本上你共享的配置是用於mod_expire，並且與調度器無關。據我記得，mod_expire不會應用頭，除非資源從apache提供（不從AEM蒸發）。
