Hello all,
I want to make some .pdf files available to visitors. and i wish non members also can download it. but i need some way to protect it from spam. as I get regular spam attack on my site. I am using the captcha for that. but i dont konw how to add captch before downloading the particular file(s).
so I need your help in any one condition
1) How can I add captcha before downloading any file?
or
2) Can I make visitor fill any form with captcha and then generate the file url to download file?
I know second form I can make in cck and then redirect it to the page where i can make that download file available. but my problem will be same again. anyone can download this file with any script for many time and make my server unnecessary busy . how can i protect my files and serve it to normal user at same time?
Thanks a lot.
