Temporary links to videos or images have no cache header set

[raRaRa]

Hey,

I noticed that temporary links don't have any cache header set. I suspect this is by design, but for use cases such as displaying media from Dropbox folder in a slideshow, it causes the browser to download large image and video files every time they are displayed. This causes un-necessary load for both my users and the Dropbox CDN/API.

It would be great if we could pass some kind of parameter that would trigger a cache header with the response.

I'm not aware of any method to enable caching with JavaScript. For images I'm using a reverse proxy to solve this, but I currently don't have one for videos.

Thanks.

Thanks for the request! I can't make any promises, but I'm sending this along to the team.

I think you can enabled a normal caching behaviour for content served from Dropbox by replacing the hostname.

so instead of

just use
