nonURLreservedspecialtoken118Deze

nonURLreserved is a term that refers to certain characters and sequences that are intentionally not used in Uniform Resource Locators (URLs) to avoid ambiguity or conflicts with the standard URL syntax. These reserved characters have specific meanings within the URL structure, such as delimiters or indicators of different URL components.

For example, characters like '/', '?', '=', '&', and '#' are reserved because they separate parts of the URL or signify parameters and fragments. The 'nonURLreserved' concept acknowledges that while these characters are essential for URL functionality, there might be other characters or combinations that, if used within a URL, could lead to misinterpretation by web servers, browsers, or other network intermediaries.

The purpose of reserving certain characters is to ensure that URLs are consistently parsed and understood across different systems. If unreserved characters were allowed to perform the same functions as reserved characters, it would create significant interoperability issues. While the term 'nonURLreserved' might not be an official designation found in RFC specifications, it conceptually represents the set of characters that are generally not part of the standard URL syntax and thus would be considered "reserved" in the sense of being avoided to maintain clarity. The set of unreserved characters in URLs, as defined by RFC 3986, includes uppercase and lowercase letters, digits, and the characters '-', '.', '_', and '~'. Any character not in the reserved or unreserved set is typically percent-encoded when used in a URL.
