So I made this FastDL (sv_downloadurl) script that gets a file from my server(s) if it's not on the webhost, compresses it and then gives it to the client.
But it seems to have various bugs, for example, sometimes it will create corrupted files. I suspect it could be a conflict caused by multiple clients trying to process the same file, but not sure. Here's the most recent error messages, had a lot of others but lost them:
[CODE][27-Oct-2010 14:05:29] PHP Warning: unlink(Gmod/maps/dm_peachs_castle.bsp) [<a href='function.unlink'>function.unlink</a>]: No such file or directory in /home/cybergmo/public_html/FastDL/process.php on line 223

Also here's the actual script. I snipped some lines but added blank lines instead to keep line number the same (for error check):

$Incomplete_Files_Extension = "incomplete"; //what extension to add to files while they are transferred/compressed.
$Incomplete_Files_Expire = 10; //Time in seconds before incomplete files may be deleted if they haven't been modified.
