CacheControlFilter doesn't work on CSS background images

I'm using OmniFace 2.7 with Primefaces 6.0. I set with CacheControlFilter an expire time of 365d for all image types (*.jpg | *.jpeg | *.png | *.gif | *.ico).

This browser caching settings seem not to apply to CSS background images that get an URL like:

.../playground/javax.faces.resource/images/smiley.jpg.xhtml

Same apply to the combined resource files (CSS and JS) that have an URL like:

.../javax.faces.resource/LONG-HASH.js.jsf?ln=omnifaces.combined&v=1544138175000

Any hints to solve this issue would be very helpful. Thanks

The answer is in the showcase and documentation of CacheControlFilter.

Important notice: this filter automatically skips JSF resources, such as the ones served by <h:outputScript>, <h:outputStylesheet>, @ResourceDependency, etc. Their cache-related headers are namely already controlled by the ResourceHandler implementation. In Mojarra and MyFaces, the default expiration time is 1 week (604800000 milliseconds), which can be configured by a web.xml context parameter with the following name and a value in milliseconds, e.g. 3628800000 for 6 weeks:

  • Mojarra: com.sun.faces.defaultResourceMaxAge
  • MyFaces: org.apache.myfaces.RESOURCE_MAX_TIME_EXPIRES

It would not make sense to control their cache-related headers with this filter as they would be overridden anyway.

I don't have much to add on this.
