Web pages that doesn't show in the proxy server

They have some very intense security on that site. If I try to proxy it, I get a message that the site is down, and if I try to use google translate, it tells me the URL is invalid.

I tried http://www.charlesproxy.com/ for a minute, and it seemed to get the requests fine, though I couldn't read the site to tell you what I was seeing, and you will of course need to recreate each HTTP request manually in screen-scraper based on what you learn from that 3^rd party proxy.
