Caching Image Renditions in Dispatcher

Hi,

 

i am facing a problem like not able to cache image renditions. Added a dispatcher for the author for performance improvement.

In Dispatcher cache i have given statlevel as 4

and the cache rule i have given to cache all the files under a project for example "react_aem_spa".

and also under invalidate rule

 

When i am trying to access http://localhost/content/dam/react_aem_spa/hiking_4.jpg the image is getting cached but when i am trying to access the rendition say http://localhost/content/dam/react_aem_spa/hiking_4.jpg/jcr:content/renditions/cq5dam.thumbnail.140.100.png  they are not getting cached.

 

Are there any configurations specifically to do so as to cache the renditions as well.

And also when i am trying to edit the tags in damadmin console for the image they are not being autoinvalidated. 

Can anyone let me know what has to be done.

 

Regards,

Sree

      Hi @sreekalyani,

      I'm no Dispatcher expert but I think the issue is with your glob expression.

      If we take the two paths you provided:

      /content/dam/react_aem_spa/hiking_4.jpg /content/dam/react_aem_spa/hiking_4.jpg/jcr:content/renditions/cq5dam.thumbnail.140.100.png

      The following glob only matches the first asset:

      /content/dam/react_aem_spa/*.*

      Instead I think you should be using this glob which matches both assets:

      /content/dam/react_aem_spa/**

      I'm a regex man and I've always disliked globs, which is why I use https://globster.xyz/ to double-check my globs 😉 Have a look!

      Matches one:

      Matches all:
