IEProxy is an .NET Proxy Manager for the Internet Explorer (IE) and all depending applications. It can handle own proxy servers and switch them on the fly. It is a TrayIcon which can quickly change your proxy settings. Requirements: Windows XP or higher,
very easy to use
It's great but it clears some important settings on Win 7 - e.g. "Bypass proxy server for local addresses", "Do not use proxy server for addresses beginning with". It would be more great if this sort of information is managed by this utility as well. Thank you for your efforts!
no trouble to install and run, works nicely.
