Hi,
Maybe you could point the link to a page that send a header("content-type: application/octet-stream") then send the document.
--- begin html ---
<a href=opendoc?doc=mydoc.doc>Document</a>
--- end html ---
--- begin php ---
<?php
header("content-type: application/octet-stream");
if ( fileexists( $doc ) ) {
readfile( $doc );
}
?>
--- end php ---
