Can't download the .mp3 file from an URL after a few days
<p>I want to download a .mp3 file on a Website with NSSURLConnection on IPhone, </p>

<p>This .mp3 URL of the file is:</p>

<p><a href="http://dl.mp3.kapsule.info/fsfsdfdsfdserwrwq3/fc90613208cc3f16ae6d6ba05d21880c/4b5244f0/b/7e/b7e80afa18d06fdd3dd9f9fa44b51fc0.mp3?filename=Every-Day-I-Love-You.mp3" rel="nofollow">http://dl.mp3.kapsule.info/fsfsdfdsfdserwrwq3/fc90613208cc3f16ae6d6ba05d21880c/4b5244f0/b/7e/b7e80afa18d06fdd3dd9f9fa44b51fc0.mp3?filename=Every-Day-I-Love-You.mp3</a></p>

<p>When I built my app, it run OK. My app downloaded the .mp3 file successful and then played it. However, after a few days, I run my app again, the app can't downloaded the .mp3 file.</p>

<p>How can I download the .mp3 file all the time?</p>

<p>Thank you very much.</p>
