I'd be so grateful if anyone can offer any advice on the following: - apologies if my terminology makes you laugh - my background is project management rather than programming...
I'm trying to route people from a generic link on a single location, to a survey where only those who clicked on the link (from this single specific location) would be able to complete a survey. (i.e I don't want anyone to be able to circulate the url where the actual survey is, and don't want anyone to be able to complete a survey unless they clicked on the link from this single specific location (and what makes it more complex is that this location is not on a website... it will be circulated on a document).
Does this even sound possible? if so would it be incredibly complex to programme this? could it be done by a cookie being downloaded when people click on the initial link and only those with a cookie get into the survey. Then as long as the link location is hidden, nobody else would be able to do the survey?.
