I'm having this same issue which I posted up a couple weeks ago without any response. http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/5-4-asset-expire-header-td5729478.html
So my first question is what did you do to resolve the issue? Secondly I am running in production mode, so I'm not sure what the cause could be. I'll have to check the cdn, but this is what google is complaining about. The images are being called from a sprite map in css where the context binding prefix can't be used. Leverage browser caching Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network. Leverage browser caching for the following cacheable resources: https://d39chrhoz7kxwa.cloudfront.net/1f1a90de-ed5_300.jpg (expiration not specified) https://d39chrhoz7kxwa.cloudfront.net/29fb2b34-55d_300.jpg (expiration not specified) https://d39chrhoz7kxwa.cloudfront.net/3902d130-3b1_300.jpg (expiration not specified) https://d39chrhoz7kxwa.cloudfront.net/75713aa2-bec_300.jpg (expiration not specified) https://www.cardaddy.com/modules.gz/autocomplete-custom.js (60 seconds) https://www.cardaddy.com/modules.gz/bootstrap/collapse.js (60 seconds) https://www.cardaddy.com/modules.gz/bootstrap/dropdown.js (60 seconds) https://www.cardaddy.com/modules.gz/bootstrap/transition.js (60 seconds) https://www.cardaddy.com/modules.gz/t5/core/messages/en_US.js (60 seconds) https://www.cardaddy.com/modules.gz/t5/core/select.js (60 seconds) https://www.cardaddy.com/modules.gz/t5/core/zone.js (60 seconds) Any thoughts?
