I'm using Charles Proxy's handy Map Local tool to develop CSS documents. This way I can immediately see my edits without having to redeploy the whole thing which in the wonderful world of enterprise-level webapps saves a considerable amount of time.
I just discovered that Map Local doesn't work with the https protocol. I have no problems with http, everything works as expected.
I'm using Windows 7, and the problem is present with every browser.
What could be misconfigured?
