I allow subjects to do multiple completes for my survey. My survey has 2000 questions, and answer type is text entry. Subjects will have 2 weeks to finish the survey. Since the survey is super long, they can always continue the survey from where they are left with before. I understand that multiple completes works for storing the information of where the subjects are left with in the survey is through browser cookies. I am concerned that, since my survey has so many questions, will browser cookies reach a limit at some moment, as a consequence, the browser fails to remember where the subjects are left with before? I just want to make sure that there is no problem of using multiple completes for my survey with 2000 questions.
