Difference between Url Encode and HTML encode

Question

What’s the difference between an URL Encode and a HTML Encode?

Answer 1

HTML Encoding escapes special characters in strings used in HTML documents to prevent confusion with HTML elements like changing

"<hello>world</hello>" 

to

"<hello>world</hello>"

URL Encoding does a similar thing for string values in a URL like changing

"hello+world = hello world"

to

"hello%2Bworld+%3D+hello+world"
