What is , in a URL?

Question

I\'m trying to understand the structure of a URL, and I\'m seeing a lot of %2C. I\'m guessing this is a result of some encoding. What does that stand for?

Answer 1

The %2C translates to a comma (,). I saw this while searching for a sentence with a comma in it and on the url, instead of showing a comma, it had %2C.
