I am new to php, but so far love it with ApacheFriends XAMPP!! I have a simple file upload script using php for an internal website.  What I need it to do is append a piece of the url its came from to the end of the uploaded file name.  It basically has to check the url its coming from, take the end of that url and append that part to the name of the uploaded file.  Then it will need to redirect that same name it used after it appended the piece of the url to the file name, and send a copy of the name to another server which is  holding the database record it will be assigned to. Does this make sense?  If not let me know! Xavior
