I have a user-defined media item pulling an image from a certain URL. That URL will serve Sharptools different images at different times. I’m using the media item as the dashboard background, so that my background can dynamically change. I am using the option to refresh the media item every X minutes.
But sometimes I’m finding that the media item / background does not refresh unless I reload the dashboard webpage. This is for an always-on display, so the browser is always displaying the dashboard. I can’t tell if the media item only refreshes on page load, or if it sometimes does but sometimes doesn’t.
I can work around this by triggering a reload when I change the image served. But it seems like the Sharptools media item refresh would be sufficient. What am I missing? Does the media item only refresh on page load? Or should it be working the way I think it should?
EDIT: Hmm. I’m remembering now what I have done for other tiles that display dynamic images. I bet I need to add a counter or something to the URL so that the browser doesn’t display cached content. I’ll try that…
EDIT2: Well, the counter approach works when the URL is embedded in html, but not when the URL is the one that I need to input into the sharptools field for the media item. So that’s not going to work. But I apparently have another media item displaying in a tile and that media item is indeed refreshing as it’s supposed to… at least I think it is. Is there a difference between how a media item displayed in a tile refreshes and how a media item displayed as the dashboard background refreshes?
