title: get request returns 403 status code even after using header
body: <p>I'm trying to scrape data from autotrader page and I managed to grab link to every offer on that page but when I'm trying to get data from every offer I get 403 requests status even though I'm using a header.
  What more can I do to get past it?</p>
  <pre><code>headers = {&quot;User Agent&quot;: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) '
                       'Chrome/85.0.4183.121 Safari/537.36'}
  page = requests.get(&quot;https://www.autotrader.co.uk/car-details/202010145012219&quot;, headers=headers)
  print(page.status_code) # 403 forbidden
  content_of_page = page.content
  soup = bs4.BeautifulSoup(content_of_page, 'lxml')
  title = soup.find('h1', {'class': 'advert-heading__title atc-type-insignia atc-type-insignia--medium '})
  print(title.text)
  </code></pre>
  <p>[for people that are in the same position: autotrader uses cloudflare to protect every &quot;car-detail&quot; page, so I would suggest using selenium for example]</p>
