JSP Current URL
<p>From some other posts, I was able to get the current URI via:</p>

<pre><code>&lt;%= request.getRequestURL() %&gt;
</code></pre>

<p>However the following doesn't work:</p>

<pre><code>&lt;%! String foo = request.getRequestURL(); %&gt;
</code></pre>

<p>I'm curious why the above doesn't work, and how to assign the current URI to a string.</p>
