Available inall subroutines.

Returns the given URL without empty parameters. Parameters are considered empty when their names are empty. Effectively, this strips a malformed query string of superfluous separators, such as a trailing ? or extra ampersands:

• /path?name=value&&=value-only&name-only becomes /path?name=value&name-only
• /path? becomes /path

Example

set req.url = querystring.clean(req.url);
