I've noticed in YSlow and PageSpeed that duplicate versions of the same file are being downloaded to render the Twitter button. I have no direct integration of Twitter features, only the AddThis code and pages are requesting the following:
http://platform.twitter.com/widgets/hub.html
https://platform.twitter.com/widgets/hub.html
Most widgets are smart enough to work out the correct protocol to use. Why am I getting two requests for the same file over different protocols increasing the page weight?
