I am developing one feature in which user will get one pdf from my site, for this I have developed a process below,
1) user will click on the link and form open in popup
2) after submitting the form one link will be sent to his email address
3) when user clicks on the link one small process of token check will be done and he will get the file
4) second time this link will not work
This whole process is working fine here my question is I want to restrict the user to get my files when user directly hit the URL link like
users can only be able to download it through that link which is in Email.
Thanks for advance.
