Fixes expressjs#6941 Previously, res.redirect(undefined) would send an invalid Location: undefined header. This change throws a TypeError when the url argument is undefined or not a string, aligning with the behavior of other Express methods like res.sendFile. Changes: - Throw TypeError when url is undefined - Throw TypeError when url is not a string - Add comprehensive tests for invalid url handling
