ProxyToy

ProxyToy allows you to switch/change the proxy server settings for Internet Explorer without having to go via the usual configuration settings. ProxyToy is controlled via a tray icon, which allows for quick switching between proxy servers. It allows you to manage your own list of Proxy servers with ports, which you can then switch to via the tray menu. Proxy Toy also allows you to disable/enable proxy settings altogether with a single click.

Requirements:

Windows XP/2003 Server/Vista, Microsoft .Net Framework V2.0
