Hi, yes all content from the upload directory can be synchronized. And for the present project, which will be the CDN, Amazon S3 ?
The concept is, we will scan all files several times a day. And we will create a data table for that to store if the file exists on cd, last time cdn updated, last time file was modified. and any link towards you upload directory will be converted where there is a update cdn file exists for that. *** and the replacement will be only done for all front site template pages and only while plugin is active.
The plugin could work with zero configuration, except the CDN server settings.
