Hi Sam,
As it is mentioned in the Google Documentation <https://cloud.google.com/appengine/docs/standard/php/config/appref#static_cache_expiration>, once the file is cached on the users end, it stays there for the time specified in the handler. Since your default expiration is set to 28 days, the cached file will expire and ready to be updated after 28 days. However, as Jason mentioned, there are common techniques that can be applied to help you save time and avoid the delay. You can refer to the following link to get a better idea of what techniques can be used which may help you in this case: https://css-tricks.com/strategies-for-cache-busting-css/ -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
