Application Cache is Deprecated

We have several boxes deployed now, and I noticed in a preview a few weeks ago that we're getting an error in the console..

"Use of the Application Cache is deprecated on insecure origins. Support will be removed in the future. You should consider switching your application to a secure origin, such as HTTPS. See for more details."

I wasn't sure at the time if it was our custom widgets or Rise Vision's Viewer. I just made some test presentations (in both the old and new editors) and only added a Text Widget. Given that the same error appears in the console, I'm assuming that Application Cache is used in Rise Vision's Viewer.

I don't foresee it being a huge problem. Given that Application Cache is the feature in question, I would assume if it does become depreciated, Displays would just not cache those items and re-download. Since we use Managed Chromeboxes, and their version of Chrome is static, I don't imagine it would change a thing there. I also don't see it as a problem for Rise Native Players. The only affect I did see would happen is the use of the Preview functionality.

Am I correct in that assumption? Is there something underway to remove the use of Application Cache in the viewer? I've determined I'm safe to ignore it, just would like to be told otherwise if needed. :)

Hi Wendi,

Thanks for bringing this to our attention. I'll need to review this with our developer team before I can formulate a response. I'll get back with you once I have something.

Thanks Wendi, your assumptions are correct.
It is in our roadmap the removal of Application Cache for the reason you mentioned.
