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

In Firefox there is Ctrl+Shift+K for the Web console, then you type

;decodeURIComponent("%2c")

• mind the semicolon in the beginning
• if you Copy&Paste, you should first enable it (the console will warn you)

and you get the answer:

","
