If I ask it to play a webpage and the content is downloaded at least once but then the media player turns off and starts back up with no internet, will the HTML page be cached?
I would like to know if my content will continue to play if some of my screens are without internet for a few days.
Generally speaking webpages need internet to be correctly displays, that being said Xibo players can use browser cache, that however will work just like browser cache ie not everything can be cached and the end result may vary depending on the webpage.
Android player can be set to cache such resources in the display profile, windows player should obey IE settings in that regard.
I’m not as concerned about the case where the screen is on and the internet goes out - from a webpage standpoint we will cache things manually ourselves.
Specifically, the case I care about is when the media player shuts down and starts back up with no internet (assume that the player had played our web page the day before so historically all content was downloaded). Will it cache the website locally to play it off the cache so it can play our images/video locally on startup - regardless of the internet connection at that time?
Are the images/videos on the webpage or are those uploaded to the CMS and added to the layout in their respective widgets?
The file based content (images, videos) that is sent from CMS to the Player will be saved in player local storage, so yes it will play those even without internet connection.
As for webpage, as I mentioned player can use browser cache - Windows will obey IE settings, Android -> Edit display profile -> Advanced -> Enable caching of Web Resources?.
