Logging dynamically served files in APACHE

[RERichard]

I'm serving up Zip and PDF files on the fly via PHP using an output such as:\[code\]header('Content-Disposition: attachment; filename="'.$project->name .'.zip"');echo($zipfile->zl_pack());\[/code\]I can't find any reference to these downloads in my APACHE logs though. Is it not logged due to being dynamic?Do I need to actually write the file to the webserver and then serve the result up to get it logged or am I missing something?Cheers,Niggles
