Percent-Encoding Explained
Percent-encoding is the mechanism behind URL encoding. Understanding it explains all those %20s.
Reserved characters
URLs reserve characters like / ? # & = for structure. To use them as data you encode them, replacing each with a percent sign and its two-digit hex code.
Keeping data separate
Encoding ensures a value containing an ampersand is not mistaken for a parameter separator. It keeps the meaning of the URL intact while carrying arbitrary text.
