Here is the project brief: I'm setting 3 TVs to the wall of my bakery store to show the menu. I have mini pc with Ubuntu at the back of my each TVs to send contents. The way that my mini PCs delivering contents is when the power is on it is going to auto start a browser and visit URl that has my menus.
Here is the problem that I have: It is perfect when the internet connection and the server that hosing my website is stable, but both of those two things is not stable at all in realty. My mini pc lose internet connection once in while, and sometimes my website is offline for some reason.
Is there any way to make a alternative to visit latest cached or saved version of URL when the browser trying to visit the URL and there is no internet connection or the website is down.
Thank you so much.
