Explanation

In SAML-based Single Sign-On (SSO), when a user attempts to access a Cisco UCM resource without an active session, UCM acts as the Service Provider (SP) and must redirect the client's browser to the Identity Provider (IdP) for authentication. This redirect is accomplished using HTTP 302 Found, which is a temporary redirect response. The browser follows this redirect to the IdP's login page. HTTP 301 is a permanent redirect, which is not appropriate for dynamic SSO flows. HTTP 300 is a multiple-choice response, and 304 means 'Not Modified' - neither is used in SSO authentication flows.
