we inherited Zend project, which hosts all static files (css, js, images, ..) on Amazon S3. Original programmer told me, that deployment is automated, but when I update new (for example) css file on server, on S3 is still old version. Same guy linked me this article: http://www.labnol.org/internet/lower-amazon-s3-bill-improve-website-loading-time/5193/, where is section "Implement Caching for Amazon S3 Files". I added ?v param for my css file, but it didn't help.
I set permissions in Amazon S3 console for user "info" (I'm logged as info@domain.tld) to: Open/Download, View Permissions and Edit permissions for mentioned css file.
Is it possible, that Zend can update static files on Amazon S3, or it's bad info? I tried to search in Zend doc, but unsuccessfully.
Thank for help
