P.S. if anyone knows how I could add more cache databases like bing cache or yahoo cache, please tell me because I couldn't figure it out.
EDIT: If anyone is willing to test the Coral CDN, I'd greatly appreciate it. For some reason Coral CDN doesn't work on my browser, so I've never tested it =`[
Very few people in my office used Google and even fewer were aware of the cache. I wrote a quick little proxy server in Python that would serve requests from Google's cache after stripping out the 'this page is a copy of...' header. I called this proxy server Doctor Who. It was quite a hit. I kept it running until people forgot to turn off proxy settings in their browser and I started seeing plaintext passwords for Yahoo mail in my logs (at the time they were plaintext).
I had specifically asked people not to access web mail while using the proxy, though, so I did take the opportunity to yell out one guy's password in the stairwell: "Hey badboy1, how's it going?"
Needed something like this for ages, thanks a ton dbz!
