Contract

  1. parseurl(req) parses pathname, search, and query from req.url
  2. parseurl(req) memoizes parsed URL on req._parsedUrl for identical url
  3. parseurl(req) re-parses when req.url is modified
  4. parseurl(req) returns undefined when req.url is undefined
  5. parseurl.original(req) parses req.originalUrl and caches result on req._parsedOriginalUrl
  6. parseurl.original(req) falls back to req.url when originalUrl is not a string
