SAML Http redirection

Hi,

We use SAML in our NW Gateway 7.4 system.Our adress is https://testerp.abc.com/saml/idp.

We use HTTP Redirect in SSO Endpoints. If we don't use HTTP redirect SAML does not work.But i have a problem here. If i call sicf service from http it is redirecting to https://testerp.abc.com/saml/idp. How can i prevent this redirection? If i call a sicf service from HTTP i don't want it to redirect HTTPS.

Thank you,

Fatih
