Temporary links to videos or images have no cache header set

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.

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

     

    so instead of

     

    <img src="https://www.dropbox.com/s/xyzabc/foo.png?raw=1">

     

    just use

    <img src="https://dl.dropboxusercontent.com/s/xyzabc/foo.png">
