title: GET command in httr not returning anything after minutes
body: <p>I'm trying to access NBA's stats api which doesn't particularly have any documentation, but after a few hacks I've figured out how to construct the URL to retrieve the appropriate data</p>
  
  <p>For example - <a href="http://stats.nba.com/stats/boxscoreadvancedv2/?GameID=0021600001&amp;Season=2016-17&amp;SeasonType=Regular+Season&amp;StartPeriod=0&amp;EndPeriod=0&amp;StartRange=0&amp;EndRange=0&amp;RangeType=0" rel="nofollow noreferrer">http://stats.nba.com/stats/boxscoreadvancedv2/?GameID=0021600001&amp;Season=2016-17&amp;SeasonType=Regular+Season&amp;StartPeriod=0&amp;EndPeriod=0&amp;StartRange=0&amp;EndRange=0&amp;RangeType=0</a></p>
  
  <p>This works perfectly fine on the browser, but when I try to use R's httr package to retrieve the same page, the command just runs forever without returning anything. Am I doing the command wrongly? </p>
  
  <pre><code>nba &lt;- httr::GET("http://stats.nba.com/stats/boxscoreadvancedv2/?GameID=0021600001&amp;Season=2016-17&amp;SeasonType=Regular+Season&amp;StartPeriod=0&amp;EndPeriod=0&amp;StartRange=0&amp;EndRange=0&amp;RangeType=0")
  </code></pre>
  
  <p>Thanks for your help in advance. </p>
