Question 1

What is URL encoding?

Accepted Answer

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a '%' followed by two hexadecimal digits.

Question 2

Why do I need to encode URLs?

Accepted Answer

URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe characters with a '%' followed by two hexadecimal digits.

Question 3

What characters are encoded?

Accepted Answer

Characters like spaces, punctuation marks, and special symbols (e.g., &, =, ?, /, #) are encoded. For example, a space becomes '%20', and an ampersand '&' becomes '%26'.

Question 4

What is URL decoding?

Accepted Answer

URL decoding is the reverse process of URL encoding. It converts the percent-encoded characters back to their original form, making the URL readable and usable by applications.
