Remove a javascript value "cached"
<p>I have a job in my javascript that I have to present the "real" content of a file with </p>

<pre><code>file.open('get', 'teste2.txt', true);
</code></pre>

<p>Unfortunately, I'm always presenting old versions of the file. The old file info is in the cache... and every time I use CTRL+R it changes... </p>

<p>How can I guaranty that I'm showing the last version of the file? Any way to clear this cache value?</p>

<p>Something like: </p>

<pre><code>&lt;META HTTP-EQUIV="Pragma" CONTENT="no-cache"&gt;
&lt;META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE"&gt;
</code></pre>

<p>But... that works :D</p>
