Ok, I've looked everywhere and I can't figure out how to do this in Litespeed. In Apache, I can easily enable this module: https://tn123.org/mod_xsendfile/ And have files forced to download when referenced/called via the browser's "Save As" feature. And everywhere I look people are pointing out to this implementation in Litespeed of the same feature: https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:config:internal-redirect But it's nowhere near the same, or it doesn't work the same way - it just opens up the file referenced, doesn't allow me to force "Save As" option on it. Here is what I have in my download.php file (that worked just fine on Apache): $file= $_GET["path"]; header("X-LiteSpeed-Location: /media/$file"); header("Content-Type: application/octet-stream"); header("Content-Disposition: attachment; filename=\"$file\""); And the file is called with download.php?path=Filename.pdf What am I missing? Or what is Litespeed missing to force this as a downloadable file instead?
