AppEngine Java caching files
<p>When I run my site on <a href="https://developers.google.com/speed/pagespeed/insights" rel="nofollow">https://developers.google.com/speed/pagespeed/insights</a>
I get the recommendation - Take advantage of browser caching for these resources with appropriate options and all my css and js are included there.
I used the following configuration in the appengine-web.xml but nothing seems to happen:</p>

<pre><code>  &lt;static-files&gt;
    &lt;include path="/**.png" expiration="1d" /&gt;
    &lt;include path="/css/*.css" expiration="1d" /&gt;
    &lt;include path="/js/*.js" expiration="1d" /&gt;
    &lt;include path="/**.js" expiration="1d" /&gt;

&lt;/static-files&gt;
</code></pre>

<p>Let me know if you need further clarifications. I do this because my outgoing traffic is getting close to 1 GB after about 10k pages views and from what I understood I should be able to have about 160k views easily..</p>
