What's The Equilavent of PHP code: header() in Asp.Net?

Question

I have a flash file that is loading data from XML file.
After I had a problem of reloading data, I found a solution to write XML code to screen with PHP code.
Here's the code I use:

<?php
header ("Cache-Control: no-cache, must-revalidate");
header ("Content-Type:text/xml");
echo '<images>';
echo '<image title="1" src="Images/01.jpg" description="1"/>';
echo '<image title="2" src="Images/02.jpg" description="2"/>';
echo '<image title="3" src="Images/03.jpg" description="3"/>';
echo '<image title="4" src="Images/04.jpg" description="4"/>';
echo '<image title="5" src="Images/05.jpg" description="5"/>';
echo '</images>';
?>  

I want to use same skill in Asp.Net aspx page. I found Response.Write() as an equilavent to echo function but how can I convert header() functions to Asp.Net code?
Thanks in advance.

Answer 1

HttpContext.Current.Response.Headers.Add

HttpContext.Current.Response.AddHeader

Answer 2

You can use Response.ContentType for the content type and you can also look into Response.Cache.SetExpires for expiring the cache immediately.
