The default expiration age of static content is enabled

The default value of the advanced setting BIResponseWrapper.staticExpiresDays is now 7 (days). Previously, the default value was 0.

With this change, static content, such as .css file and .js files, stays in cache for seven days before it expires. This can reduce significantly the download time of static content.

This change applies only to an installation for which no value is already set:

  • If your environment includes web servers and a value is already set, that value will take precedence.
  • If you are upgrading to release 11.2 and BIResponseWrapper.staticExpiresDays was previously set, there is no impact.
Tip: If your static content is out of sync with the server side, refresh the browser or delete the local cache in your browser.

If you want to change the expiration age of static content, you can change the value, in days, of the BIResponseWrapper.staticExpiresDays.
