SSL & XML File Download Problem

Hi, I have a site that allows users to download xml files. I have the following php script which prints the results of the query to the browser. As the header is chaged to XML it forces the browser to ask the user if they want to download the file rather than outputting the results straight to the browser: <?php header('Content-type: text/xml'); header('Content-Disposition: attachment; filename="test.xml"'); // doquery $xml = "<?xml version=\"1.0\" ?>\r\n"; // add query results to $xml echo $xml; ?> This was working fine until i added an SSL certificate to my site, now I get the following error message: Internet Explorer cannot download ..._download.php?id=4723 from www... .com Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found... Any ideas?
