title: Viewing "Page Source" shows different HTML than cURL
body: <p>First of all, my problem is different from this one: <a href="https://stackoverflow.com/questions/10758105/difference-between-curl-and-web-browser">Difference between cURL and web browser?</a> </p>
  
  <p>I use my Chrome browser to visit: <a href="http://www.walmart.com/search/browse-ng.do?cat_id=1115193_1071967" rel="nofollow noreferrer">http://www.walmart.com/search/browse-ng.do?cat_id=1115193_1071967</a> And then, I view the page source to get like:</p>
  
  <p><code>&lt;a class="js-product-title" href="/ip/Tide-Simply-Clean-Fresh-Refreshing-Breeze-Liquid-Laundry-Detergent-138-fl-oz/33963161"&gt;</code></p>
  
  <p>However, I didn't find this kind of info from command line:</p>
  
  <pre><code>curl "http://www.walmart.com/search/browse-ng.do?cat_id=1115193_1071967"&gt;local.html
  </code></pre>
  
  <p>Does anyone know why cause the difference? I am using Python scrapy selector to parse the webpage.</p>
