We're using CDN for Joomla in combination with Bunny CDN and they support URL Query String caching.
We have a few busy sites that may require a more flexible caching solution. It appears URL Query String caching + the File Versioning option in CDN for Joomla may be a solution to us.
However, the notification that File Versioning can have a negative effect on the loading time of the website is not appealing:
Are you able to give us one or more use case examples on how this negatively effects?
My understanding would be that let's say a new change to a css file would trigger this file to get a new datestamp and has to be cached by the CDN.
Similar for how let's say an image upload using being uploaded with the same name / overwrite would require the CDN to again cache that image.
hen using query strings, there might be some browsers (or depending on the browser settings) that will not cache these files locally. So that could impact the loading time.
But seeing that pretty all media files in Joomla use query strings anyway, I wouldn't worry about that too much.
