title: Python requests - 403 forbidden - despite setting `User-Agent` headers
body: <pre><code>import requests
  import webbrowser
  from bs4 import BeautifulSoup
  
  url = 'https://www.gamefaqs.com'
  #headers={'User-Agent': 'Mozilla/5.0'}    
  headers ={'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36'}
  
  
  response = requests.get(url, headers)
  </code></pre>
  
  <p><code>response.status_code</code>  is returning  403. 
  I can browse the website using firefox/chrome, so It seems to be a coding error.</p>
  
  <p>I can't figure out what mistake I'm making. </p>
  
  <p>Thank you. </p>
