WebDriver - Proxies, HAR Files, JS Executors ... and yes, Flex/Flash

All WebDriver does is driver browser. Nothing more, nothing less. Which means there are a lot of things that are out of scope to the Selenium project that are handy to have for scripting -- like HTTP response codes and hooking into 3rd party application execution environments (like Flex and Flash). WebDriver does provide the means to do both of these; if you know how. I'll cover how to wire your scripts through a scriptable proxy (BrowserMob) to get at the raw HTTP traffic information, as well the JS Executor which allows for such magic as driving Flex and Flash through WebDriver.
