Hi,

We want to stop the browser to check if modified. When we want to change the image on S3, we will change the name of the image for version control.

We would like the browser to download once and never check the image again. Is this something that has to do with the Etag, Last Modified or the Age headers?

Thanks Smile
It's actually the Expires and max-age headers.

Thanks,
