ProxToggie is a free application for your Mac that will toggle the web proxy ON/OFF for Ethernet and AirPort. If you run ProxToggie when the proxy is OFF, it turns the proxy ON and vice versa. You can open up the proxies preferences pane while running ProxToggie and see it check and uncheck the setting.NOTE: This program will save a file of zero bytes in the root level of your hard disk (where you see Application, Users, etc.) named \"_proxyOn\". This can be useful if you want to know if the proxy is ON (you won\'t see a file unless the proxy is ON).
