What does this java line do?
<pre><code>response1 = CustomHttpClient.executeHttpPost("http://gamesdsxd.com/appfiles/login.php", postParameters);
String res = response1.toString();
res = res.replaceAll("\\s+", "");
</code></pre>

<p>I'm wondering what \s+ does and what this replaceAll does and why it is needed.</p>
