URL escaping

Noun
DefinitionURL escaping is a standardized mechanism used to encode information within a Uniform Resource Locator (URL) that might otherwise conflict with the URL's syntax or have special meaning. This process involves replacing certain characters, typically non-alphanumeric or reserved characters, with a percent sign (%) followed by their two-digit hexadecimal representation. It ensures that URLs are correctly interpreted by web browsers and servers, preventing errors or misinterpretation of path, query, or fragment components. Characters such as spaces, question marks, and ampersands, when part of data rather than URL structure, frequently require escaping. Without URL escaping, complex or non-standard characters in a URL could lead to broken links or incorrect resource access.
Example

"To ensure the search query was correctly processed by the web server, the browser performed URL escaping on the spaces and special characters in the user's input."
