I use Amazon S3 and CloudFront. I have static images and users downloaded images(every hour + 100 images).
I need to set Cache-Control http header for all bucket.
I search in google, but I cant find any instruction, how to do this.
Yes, I know about MetaData in file Properties, but I need MetaData for all bucket (+ new files in future).
If it is not possible to do in Amazon console, is there any open source solutions?
Thanks!
S3 does not have a mechanism for setting global bucket metadata on existing or future objects. Your code needs to set this when the objects are created.
You can add it to existing objects using the "put/copy" operation of the API, which allows you to copy an object onto itself, with modified metadata, without actually downloading and re-uploading the object.
http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html
Regarding open-source solutions, there might be, but the only possible mechanism they could use would be to perform the same actions -- iterating through the bucket and updating each object's metadata via the API. In any event, though:
