What is URL Encoding?
URL encoding converts characters that are not allowed in URLs into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
When to Use URL Encoding?
URL encoding is necessary when: - Sending data through URLs (query parameters) - Handling special characters in URLs - Working with multilingual content - Ensuring safe transmission of data
Common URL Encoding Examples
| Character | URL Encoded |
|---|---|
| Space | %20 or + |
| & | %26 |
| = | %3D |
| ? | %3F |
| / | %2F |
| @ | %40 |
