Does Percussion or maybe server force clear cache when we launch major update on the homepage? I do not want to remind 1000k users to clear their cache. Any solution?
Cache control is typically controlled by the web server settings so will depend on your deployment, web server used, and the settings for the website host on the web server.
See the links below:
For Apache web servers:
For IIS web servers:
Percussion publishes static content so if the web server is configured to use ETAGS and Modified Since headers based on the modification date of the file end users should pickup the changes.
