I am working on an app where users are only allowed access if they click through from certain URLs. I.e. I need to authenticate by using the referral url and I am using Request.UrlReferrer to achieve this.
I am guessing that the Request.UrlReferrer can be tampered with by malicious users to gain access...
Is there any way I can achieve the above scenario securely?
Look forward to your replies.
