Hi, I have a simple scenario to tackle where a user hits a cfm page and has to answer a question, the same user must not be able to repeat this process though. (would like to avoid the user having to register any information i.e. user name or email address etc for identification).
I have tried IP checks but delving deeper resulted in a heap of problems related to ensure I got the users local ip and not proxy, then HTTP_X_FORWARDED_FOR is a no no ant REMOTE_ADDR returns the same ip on different machines within a company network. I have also tried the storing a cookie on the users computer but obvious problems occur there with browsers refusing cookies or deleting them. I finally tried ClientManagement using a database and enabling in CFAdmin, but realised that this checks a users client variables in the database against cookies which once again means failure. So, is there any methods to identify a user and reject them if they have previously accessed that particular application, or accept and store that they have visited if they have not accessed the application?
