How to configure cache-control headers for objects in a bucket during HTTP requests

Scenario descriptionScenario description

You need to set up cache-control headers for objects in the bucket during HTTP requests.

SolutionSolution

You can add the Cache-Control header to system metadata during the upload or modification of an object in the bucket. For more details about object metadata, see the documentation.

To add Cache-Control to a previously uploaded object, you can use the s3cmd utility.
To do this, run the following command:

s3cmd --add-header 'Cache-Control:3600' modify s3://<your-bucket-name>/object-name.

To add the Cache-Control header during the object upload to the bucket using s3cmd, specify the --add-header parameter:

s3cmd --add-header 'Cache-Control:3600' put local_file s3://<your-bucket-name>/object-name.

You can also use the AWS CLI utility to add the Cache-Control header.
Example command for AWS CLI:

aws --endpoint-url=https://storage.yandexcloud.net s3 \
cp local_file s3://bucket_name --cache-control 'max-age=3600'
