-As LiteSpeed Cache is designed to avoid hit PHP backend, ​therefore ​there is no way for cache module to know what value it is stored in PHP session.+Why? LiteSpeed Cache is designed to avoid hitting the PHP backend. Therefore, there is no way for the cache module to know what value is stored in PHP session ​for any visitor other than the first one to load the page.

-To make this to work , it will require ​code change ​in plugin to make it store values ​in cookie and set LiteSpeed Cache to [[litespeed_wiki:​cache:​developer_guide:​cache-vary|vary on cookie]].+To make this to work, code change ​to the third party plugin is required. The developer can change the plugin to store the value in cookie and then LiteSpeed Cache can be set to [[litespeed_wiki:​cache:​developer_guide:​cache-vary|vary on that cookie]].
