Android File Service HTTP Response Headers - no-cache?
I've uploaded some images via file service api (Android Java) into the file section of backendless. In my application I want to check the tag max-age in Cache-Control Header. Only if a certain value is exceeded I want to download the image again, to make the application faster and reduce traffic. My caching function seems to work - but unfortunately not with my files at backendless. All files in backendless file section have the following Headers related to cache
Cache-Control: no-store, no-cache, must-revalidate, private
Is there a way to change those file headers either in backendless or when uploading files via android API?
Any help would be much appreciated.
Thank you very much for your strong support!
