Smoothwall's team of intrepid web-wranglers have recently noticed a change in Twitter's behaviour. Where once, it was impossible to differentiate the resources loaded from twimg.com, Twitter now includes some handy sub-domains so we can differentiate the optional user-uploaded images from the CSS , buttons, etc.
This means it's possible to prevent twitter loading user-content images without doing HTTPS inspection - something that's a bit of a broad brush, but given the fairly hefty amount of adult content swilling around Twitter, it's far from being the worst idea!
Smoothwall users: Twitter images are considered "unmoderated image hosting" - if you had previously made some changes to unblock CSS and JS from twimg, you can probably remove those now.
We all work in the internet security industry, and as such we're involved with a wide range of technologies, markets and people.
