For SSL-based authentication and data encryption in Cosminexus HTTP Server, see 7.2.5 SSL setup with Cosminexus HTTP Server in the uCosminexus Application Server Security Management Guide. For SSL-based authentication and data encryption in Microsoft IIS, see 7.2.6 Microsoft IIS setup (in Web redirector environments) in the uCosminexus Application Server Security Management Guide. You can use this functionality only in the Web redirector environment.
