Hi Jose
Thanks for responding quickly.
I understand your reasoning on this and agree for most instances this is a good approach.
There are however occasions where precaching a list of files is needed. In my scenario the user turns up at a site with no mobile data available. They can connect to wifi (which again is not connected to the internet) which serves out a web site. The wifi is only available in a small area and the user needs to play different audio tracks in non wifi areas as they explore the site.
It looks like we will have to write the code ourselves rather than use your plugin.
Thanks again for creating such a useful plugin that I am sure a lot of WordPress users will find very useful.
Best Regards
David
