Is it advisable to restrict file downloads to only one connection in PHP, considering the Hypertext Transfer Protocol principles?

Restricting file downloads to only one connection in PHP may not be advisable as it goes against the principles of the Hypertext Transfer Protocol (HTTP), which allows for multiple connections to be made to improve speed and efficiency. Instead, it is recommended to implement proper authentication and authorization mechanisms to control access to files. 

// Check for authentication and authorization before allowing file download
if($authenticated && $authorized) {
    // Code to initiate file download
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="file.txt"');
    readfile('path/to/file.txt');
} else {
    // Handle unauthorized access
    echo "Unauthorized access";
}
