title: Problems getting network traffic logs from loaded webpage using python and webdriver
body: <p>Using Python and webdriver (selenium)</p>
  
  <p>I need to load a web-page in webdriver and capture network traffic from it.</p>
  
  <p>I have read alot of useful information by googling that helped me on the way.
  ie. <a href="https://stackoverflow.com/questions/52633697/selenium-python-how-to-capture-network-traffics-response">Selenium - python. how to capture network traffic&#39;s response</a></p>
  
  <p>I can get some of the logs, but i can not get the network-traffic-log</p>
  
  <hr>
  
  <p>Basically, i do something similar to the below:
  (i can not show all the code here, but this basically it):</p>
  
  <pre><code>d = DesiredCapabilities.CHROME
  d['goog:loggingPrefs'] = {'browser': 'ALL'}
  
  driver = webdriver.Chrome(chrome_options=my_options,
                            executable_path=my_driver_destination,
                            desired_capabilities=d,
                            service_args=["--verbose"])
  </code></pre>
  
  <p>Open a webpage and perform some magic</p>
  
  <pre><code>driver.get("http://somethingsomething")
  </code></pre>
  
  <p>By calling get_log at this point, can i get some logs out (depending on what state my loaded page is)</p>
  
  <pre><code>logs_for_me = driver.get_log("driver")  # "performance" "browser" "server" "client"
  </code></pre>
  
  <p>However, i can not find any network-logs at this point (only driver and browser -logs). What am i missing ? </p>
  
  <p>If i cant' get it as a parseable object, can i force the driver itself to spool the log to file so i can get it there?</p>
