Does this plugin supports video files caching?

Do you mean a static video file hosted on your server that would otherwise require a backend process to retrieve? Then yes, the Cache Enabler delivers a static HTML file to avoid these resource intensive processes.

Yes we host our videos in our servers under s2member secure folder and other folders and what I want to do is cache those files by caching plugin such as cachify via HDD cache. But cachify required some additional htaccess code for hdd cache and it went our site 500 internal server error and i am refused to use cachify. Maybe your plugin would do the same as cachify?

Hi you didnt reply to me?
Can cache my uploaded video files by this plugin?

I use both s2member and a folder to store our video files on our server.

Static assets (such as image or videos) are not changed or specifically cached by the Cache Enabler as there is no need for that.
