Hello, Consider currently I am using mod_expire to set a HTML file to 15 minutes expire. The file change quite frequently, sometime maybe changed within 15 minutes so I want my user to see the change as soon as possible... sometimes the file does not change even for 10 days! So what expire value I should set? Thanks. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
