<p>I have a script that works fine on my test server (using IIS6). The script processes an ajax request and sends a response with the following line:</p>

<pre><code>header( 'application/javascript' );
</code></pre>

<p>But on my live server, this line crashes the page and causes a 500 error.</p>

<p>Do I need to allow PHP to send different MIME types in IIS7? If so, how do I do this? I can't find any way on the interface.</p>

The header is incorrect, try this instead:
```
```
header('Content-Type: application/javascript');
```
```
