title: Java Selenium: how can I get the HTML of a webpage without first loading the page?
body: <p>Using Selenium WebDriver for Java, is it possible to get the HTML of a webpage given a specified URL?</p>
  
  <p>I know that, once a webpage is loaded in a browser, the HTML can be obtained using WebDriver.getPageSource(). However, for improved efficiency, is it possible to obtain the HTML without loading the page in a browser first?</p>
