title: Does the browser instance from mechanize cache?
body: <p>I am doing some webscraping with the mechanize browser and using the following code. I realized in some cases we keep getting the same page, although the remote page is already changed. So my question is: </p>
  
  <ol>
  <li>Does mechanize broswer instance cache page by default (in some config)? </li>
  <li><p>If so, how can we change it, or is there a way to avoid caching (apart from creating the browser instance every time in the loop we webscrape)</p>
  
  <pre><code># put int login detail and submit, return a mechanize.Browser instance 
  browser = _login() 
  # main loop
  while True:
      rsp = browser.open(URL)
      html = rsp.read()
  </code></pre></li>
  </ol>
  
  <p>thanks</p>
