Download unknown files without touching MIME definitions

nova4x

I had to put some links in my PRODUCTION FLARUM site, to download Metatrader 4 files, a forex trading platform

By default the "mq4" extension of the metatrader is interpreted as a text file by all the browsers

So if i put the direct link or

<a href="https://nova4x.eu/assets/files/uploads/SpecialForce-November-V02.mq4">SpecialForce November V02</a>

All the browsers display the text page, beside the code loses the required format and cannot be copied and pasted as a new metatrader program

I tried the new DOWNLOAD tag, but it works only in Chrome and few others

<a href="https://nova4x.eu/assets/files/uploads/SpecialForce-November-V02.mq4" download>SpecialForce November V02</a>

So I coded this simple down-november.php file

<?php
    $file = 'https://nova4x.eu/assets/files/uploads/SpecialForce-November-V02.mq4';
    header("Content-Description: File Transfer"); 
    header("Content-Type: application/octet-stream"); 
    header("Content-Disposition: attachment; filename='" . basename($file) . "'"); 
    readfile ($file);
?>

...and I put the call to the php file in the links, i.e.

<a href="https://nova4x.eu/assets/files/uploads/down-november.php">SpecialForce November V02</a>

So I obtain the right download without touching anything else

Only a two cents solution, but It could help others
