note 76701 added to function.header

I've got a question. I have a file hosting site and I've run into a nice problem when downloading files using the header function. Here is the code I use for downloading the file <?php $file = "/path/to/file.ext"; header('Accept-Ranges: bytes'); header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); header('Content-type: ' . $fileDownloader->mime_get_type($file) . '\r\n'); // Custom mime type function header("Content-Length: ". filesize($file) . "\r\n"); header('Content-Disposition: attachment; filename="' . $v_name . '"'); header("Content-Transfer-Encoding: binary\n"); readfile($file); ?> As far as downloads are concerned, everything download perfect. The only issue is that once the download begins, that user can not do anything else on the website until the download is either complete or canceled. Any ideas? ---- Server IP: 208.69.120.35 Probable Submitter: 64.81.93.110 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/76701 Del: integrated -- https://master.php.net/note/delete/76701/integrated Del: useless -- https://master.php.net/note/delete/76701/useless Del: bad code -- https://master.php.net/note/delete/76701/bad+code Del: spam -- https://master.php.net/note/delete/76701/spam Del: non-english -- https://master.php.net/note/delete/76701/non-english Del: in docs -- https://master.php.net/note/delete/76701/in+docs Del: other reasons-- https://master.php.net/note/delete/76701 Reject -- https://master.php.net/note/reject/76701 Search -- https://master.php.net/manage/user-notes.php
