Wordpress LScache Plugin: introducing new cache to browsers

Hi. how can I tell the users browser that there is a new version of my website available? I purge my cache and there is a crawler that creates a new cache of my website. right? please tell me in the most basic way so I can understand. Thank you for the support in advance. Hi, a dynamic page like wordpress, should NOT be cached by browser this is a server side cache system by that saying , all the cache/purge operation were done on server side Best regards,
