Message288118
I compared the behavior of IE and urllib.
I put different addresses to the <proxy bypass list> ("Do not use proxy server for address beginning with" setting), made different requests through IE and urllib and watched if the proxy was bypassed.
IE doesn't even make a forward dns lookup for the hosname given to check whether it should bypass proxy, whereas urllib does.
For example:
proxy_bypass_list request IE bypasses proxy urllib bypasses proxy
