title: How do you run headless chrome and a proxy using selenium in python?
body: <p>My python script has the headless chrome in selenium up and functional but how, if possible, can I use a proxy as well? How can I pass the proxy host port to my headless chrome browser?</p>
  
  <pre><code>options = webdriver.ChromeOptions()  
  options.add_argument('headless')  
  browser = webdriver.Chrome(chrome_options=options)
  </code></pre>
  
  <p>How do I use the proxy host port with selenium and mainly headless chrome? Thanks!</p>
