How to make PDF file read only when downloading?
We have two users in system. One user can submit all fields in pdf form and save the pdf file and upload it to the system. Other user can download that pdf file for assessment purpose. I have used send_file method to download pdf. My question is that How can I make same pdf file read only while downloading so that second user should not edit pdf file?
