title: IE not accepting cookie from Tomcat servlet filter
body: <p>I have a servlet filter set up to handle various ways of entering my website.  One goal of the filter is to set a cookie on entry.  The below code works perfectly in Chrome, Safari and Firefox but IE doesn't seem to like it.  Due to some constraints I am not able to set the cookie with JavaScript.</p>
  
  <pre><code>Cookie cookie = new Cookie(COOKIE_NAME, COOKIE_VALUE);
  cookie.setPath("/"); //Note: I've tried removing this.
  cookie.setDomain(SITE_DOMAIN); //Note: I've tried removing this.
  response.addCookie(cookie);
  </code></pre>
  
  <p>I've tried different combinations of max age and expiration date, but nothing seems to work.  I've stepped through on a debugger and I'm sure the code is being executed.</p>
  
  <p>Also, for the record I'm using Tomcat 6.  Cookie name and value are both strings of around 10 chars length.</p>
