Download and Upload of Files

Hi there guys.... i developed an app that uses AJAX, ActiveX objects and PHP to download and upload files from local machine to the server... everything works great, i can transfer office files and even exe files. The problem i'm face is to transfer mp3 files and pdf files... anybody already try do something like these?? If not, how can i get a file with php without the use of a html form or even the enctype = multipart/form-data?? To get the files i'm using $GLOBALS["HTTP_RAW_POST_DATA"], because the file_get_contents give the memory size error even if i send half of the memory size allowed... And another question, binary data in mp3 or pdf files have some character that can give some type of error when send over the internet??? thanks for any help! -- * Rodolfo De Nadai * * Analista de Sistema Jr. - Desenvolvimento * *Informática de Municípios Associados S.A.* Seu governo mais inteligente rodolfo.denadai@ima.sp.gov.br <mailto:rodolfo.denadai@ima.sp.gov.br> - www.ima.sp.gov.br <http://www.ima.sp.gov.br/> Fone: (19) 3739-6000 / Ramal: 1307
