/*
Cookie implementation top step
One user can only step on each article once in a day.
Cookie is used.
However, when I clicked another article, I could step on it. But after I refresh the original article, I could step on it again. It wasn't a day before.
It turns out that cookie is re-instantiated when another article is clicked.
