Comment 4 for bug 590621

The CSS is requested by all but 4 pages on launchpad. the spinner doed not approach that level of ubiquity. I see many scripts and support markup hard code the image. I am sure this is because lazr.js is not Launchpad. The spinner is mangaged by the resource directive and is intended to be cached by the proxy. mthaddon setup the proxy rules a few years ago.
