Frequently Asked Questions
Which characters need encoding?
Characters like spaces, &, =, ?, /, and non-ASCII characters must be encoded. Letters, numbers, and -_.~ are safe.
What is %20 vs +?
%20 and + both represent spaces. %20 is used in path segments, while + is sometimes used in query strings (form encoding).
Should I encode the entire URL?
No. Only encode parameter values. Encoding the entire URL will break it by encoding / and : characters.
