Hello everyone Good Morning, I done adding expire header by put the following code into my product model. :s3_headers => { ''Cache-Control'' => ''max-age=315576000'', ''Expires'' => 10.years.from_now.httpdate }, But its work only while i add new product and image. Already i have 100 of products and images. How can i add expire header for those which already exist products. Please advice.
