Frequently asked questions
When do I need URL encoding?
Whenever a value goes into a URL and might contain spaces, ampersands, slashes, or non-ASCII characters, which would otherwise break the link.
What is the difference between encoding a component and a full URL?
Encoding a component escapes characters such as / and ? as well, which is right for a single query value but would corrupt a complete URL.
