But Still this problem persists in another way not through query string, I have a serious issue in my site where people are hacking the files with out paying with paypal. When I try to test this process I have ensured that the paypal payment system is not secured before going to paypal when I try with the specific success url I can see the download files in the page. I am worried about this unsecured payment process when I use paypal. Can you please help me to avoid this situation?
I have installed the new version 1.0.1 in my Oscommerce ebook store today, previously people are hacking my files without paying through paypal. Now can I expect this does not happen again?
Thank you,
Harris
