Simply put, I'm using a plugin that I'd like to host on a different server from the one my site is on. I'd like to point joomla to the plugin content stored on that other server, not in the plugin folder of my Joomla site.
Why would I want to do that? Well...
Background: I have been using Joomla since version 1.5, and way way back then, I started using mp3browser.
I've been updating it to function myself for years, because I haven't found a better way to make nice little lists of audio files for my users to interact with. These are recordings I have made myself, that my organization owns.
I've been hit with a warning from my hosting provider, that storage of mp3s is no longer allowed (it's considered bulk storage, even if the files are linked), so I need to move them to another server.
The plugin I'm using browses then lists the server's files within a specified folder, including media tags for playback on each file. As such, the php files need to be executed by the server that also hosts the files.
My wonky idea is to move the plugin to my other server and have Joomla point itself to that server for that particular plugin (folder).
