Hey Guys.
I was trying to send a custom header to another page for accessing its api.

I am using this HttpResponse::setHeader ( 'customname', 'myvalue' );

What class do I need to use for this? Does PHP5.1 and above have this inbuilt or do I need to include some particular class to use this? How do I create an instance of this class? Any help is appreciated.

try to use
<?php
header("location: index.php");
exit();
?>
