This is a Chrome extenstion which helps you clearing DNS cache by one click. By using it, you don't need to open the page(chrome://net-internals/#dns) and click the button "clear host cache" and open the page(chrome://net-internals/#sockets) and click the button "Flush socket pools" any more.
To use it, it requires command line flag --enable-net-benchmarking when you start the chrome browser.
