I have a piece of PHP code that serves digital downloads securely (usually .zip files) using a download code. I moved this from another server, made all necessary modifications and so forth.
It seems to be working fine for most people. But some are experiencing corrupted downloads. I cannot recreate this on any of the two Macs or PCs at home, but I have had enough customers complain that I know this is not imaginary.
Some are complaining of “Safari Domain 0,” most are citing a corrupt zip when they download the file.
I have recreated the php.ini from the original server. Obviously it’s not identical, but all configurable settings are the same.
I’ve checked headers using a Firefox extension and am not getting any irregularities.
I’m hoping someone out there knows exactly what is going on and can help me. Thanks everyone.
