Python Browsermob Proxy With Ie Captures Incorrect Har?

I am currently trying to use BrowserMob Proxy (v2.1.1) + Selenium (v2.5.3) for Python (v2.6) to test page load times and output them to HAR files. I need to test both Chrome and IE

Solution 1:

You need to ensure that the cache of IE is clean before launching the browser:

desired_capabilities  = webdriver.DesiredCapabilities.INTERNETEXPLORER
desired_capabilities ["ie.ensureCleanSession"] = True
driver = webdriver.Ie(capabilities=desired_capabilities )

Note that you are reading the metrics on the proxy. Thus you are only measuring the response times of each request and not the page load times.
