Well, this is one more reason for urging all browser vendors to support
proxying over https. This will put an end to this redirection madness
which prevents most HTTP agents from working in such environments (eg:
firefox cannot even update itself at a customer's due to such proxies,
so everyone uses outdated versions until they decide to download the full
image again).
