Hi, I am working on a download page where a PHP tracking program will keep record of the number of downloads for a particular file.

Can you tell me the keys on how to redirect people to download a file while increments the number of downloads?

I read somewhere that the URL is like this
http://my.url.com/download.php3?=/files/xxx.zip

but people click on this URL, the program will prompt the user of the location for which the file will be stored and a number will increment by one in the database.

How do I do this? Also, I wanna to do this for 2 obvious reasons:
1. To avoid people linking to my file
2. To keep track of the number of downloads

Thanks
