If a patron gives you a link from SuperSearch using the URL from their browser instead of the permalink, you might get an error message from EBSCO instead of the page you want.
Sometimes, but not always, it's possible to recreate a working link from a bad one. If it's possible, this tool will do it.
(The link from here also will expire -- it's not a permalink either!)
