I’ve written a code in php, which is used in downloading link like https://example.com/dl.php&file=test.zip. Here the file dl.php checks the HTTP refer, if it is allowed then it download the file from “up” directory. it gets the file name from “file” URL parameter and check the file in “up” directory and download it.

Everything is working perfectly, but when the file is being downloaded it doesn’t show File size and Resume option. I am using WHM/cPanel with Engintron. Its fresh server installation. Same script works perfectly on AApanel but doesn’t show file size here on WHM. Any help would be highly appreciated.

here is my code for dl.php
