Some URLs might contain ampersand (&)-separated parameters. If each '&' separated parameter is not followed with an equal sign (=), the APM system does not recognize it as a proper query string, and the redirection from the primary virtual server back to the secondary virtual server will be incorrectly parsed.
Customer will not be able to login with URLs that include an '&' that is not followed by an '='.
This problem occurs with multidomain SSO.
To work around the problem, URL-Encode "&" and "=" in the original URL before passing it to APM. Or, follow every parameter with "=" or "=value". Both workarounds require application changes.
