URLkodade

URLkodade, also known as URL encoding, is a technique used to convert characters in a URL into a format that can be transmitted over the internet. This process is essential because URLs are restricted to a specific set of characters, primarily alphanumeric characters and a few special characters like hyphens, underscores, and periods. Characters outside this set, such as spaces, punctuation marks, and non-ASCII characters, must be encoded to ensure proper transmission and interpretation.

The encoding process involves replacing these characters with a percent sign (%) followed by two hexadecimal digits representing the ASCII value of the character. For example, a space is encoded as %20, and an ampersand (&) is encoded as %26. This encoding scheme is defined by the Uniform Resource Identifier (URI) specification, which is a standard for naming resources on the internet.

URL encoding is commonly used in web development to handle user input, such as form data and query parameters, which may contain characters that are not allowed in URLs. By encoding these characters, developers can ensure that the data is correctly transmitted and interpreted by web servers and browsers.

In summary, URL encoding is a crucial technique for ensuring the proper transmission and interpretation of URLs on the internet. It involves converting characters outside the allowed set into a format that can be safely transmitted, using a percent sign followed by two hexadecimal digits representing the ASCII value of the character. This process is defined by the URI specification and is widely used in web development to handle user input and query parameters.
