<p>My question is how can I make this available to students at home? </p>
<p>The server is running Windows Server 2008 R2. I've got PHP, Apache, and MySQL working together.

<p>I'm creating a site where you can upload a zip file and we will extract it and provide a method of viewing your html site before viewing it. I can see my main problem is going to be bandwidth right now and that is due to the fact that once you access the <a href="https://github.com/valums/file-uploader" rel="nofollow">Valums File-Uploader</a> on our page you can upload infinite files.</p>
<p>I've already changed the script so that it opens a session and grabs the persons username and no matter what they upload it goes in the format of:</p>
<pre><code> if ($this->file->save($uploadDirectory . $_SESSION['myusername'] . '.site.' . $ext)){
</code></pre>
<p>This makes it so no matter what they upload it gets created in the format of username.site.zip.</p>

<p>For Example:</p>
<pre><code>public class Rectangle

private double width = 10.0;
public Rectangle(double length, double width){
this.length = length;
this.width = width;

//this is the copy constructor what exactly the argument here? is it the object ref it self? please explain what happening here. and the use
public Rectangle(Rectangle ref){
this.length = ref.length;
this.width = ref.width;
}
</code></pre>
<p>this is what I see all the time. but I don't understand the code at all!
<code>ref</code> is it going to be created in the main program?</p>
<p>let say this is the main program</p>
