Frequently Asked Questions

What is URL encoding?

URL encoding (percent-encoding) converts characters that are not allowed in URLs to a %XX format where XX is the hexadecimal ASCII code. For example, a space becomes %20.

When do I need URL encoding?

Any time you include user input in a URL query string, you must URL-encode it. This prevents malformed URLs and potential injection attacks.
