how to respond to a http request
Note that if you output data before sending the response then you will get a warning saying: Cannot modify header information - headers already sent. So do not echo any data in your responding script.
<?php<note>Thank you for posting your data! We love php!</note>');
//process the request by fetching the info
$headers = http_get_request_headers();
$result = http_get_request_body();
//do stuff with the $headers and $result variables....
//then send your response
HttpResponse::status(200);
HttpResponse::setContentType('text/xml');
HttpResponse::setHeader('From', 'Lymber');
HttpResponse::setData('<?xml version="1.0"?>
HttpResponse::send();
?>

I was having a problem with the bytes appended to the output, using the given example.
<?php
...
HttpResponse::setFile('sheet.pdf');
HttpResponse::send();
?>
Content-Length mismatch: Response Header claimed x bytes, but server sent x+5 bytes.
Adding an exit statement solved this problem.
