Support » Plugin: New Nine Adaptive Images » W3 Total Cache CDN Conflict

  • Hello,

    I am using your plugin, and I love how it works, but when I enable the CDN (I am using Amazon Cloudfront) functionality in the W3 Total Cache plugin, the images on my mobile device do not size down to the appropriate image. I am guessing that this has something to do with the images being replaced with ones coming from the CDN?

    Is there a way to Have both work?

  • Just a quick addition … it is actually the entire W3 Total Cache plugin, not just the CDN. If any of the settings are enabled, the New Nine Adaptive Images plugin stops working.

    My mistake … i narrowed the issue down to the CDN, more specifically ONLY the “Host attachments” and “Add canonical header” settings.

    The photo files being uploaded to the media library are being added to the CDN and the cached Nine Adaptive Images photo files are not being served to the mobile site, the photos from the CDN are being served.

    Any thoughts?

    I don’t think this plugin can work with a CDN. The plugin uses a server side library to serve up a correctly sized image on the fly – it can’t do that if it’s coming from a CDN.

    From: (the library behind the plugin)

    Adaptive Images relies on the server being able to intercept requests for images, do some logic, and then send one of a given number of responses. Content Delivery Networks are generally dumb-caches, and they won’t allow that to happen. Adaptive Images will not work if you’re using a CDN to deliver your website.
