Why does this redirect not work? Java SSL

Question

Hello,

I have a page HelloWorld.xhtml in /Login folder. I have set this constraint for this page. I am using jdbcRealm:-

  <user-data-constraint>
            <description/>
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>
        </user-data-constraint>

I have a filter on this page and in filter i do this :-

 if (objHttpServletRequest.isUserInRole("Admin")) {

                objHttpServletResponse.sendRedirect("http://blogger.blogdns.com:8080/Blogger/Admin/home.jsf");
            }
            else if(objHttpServletRequest.isUserInRole("Member")){
                objHttpServletResponse.sendRedirect("http://blogger.blogdns.com:8080/Blogger/Member/home.jsf");
            }

In spite of http protocol which i have specified for redirect, it always redirects using https, so the url becomes :- https://blogger.blogdns.com:8181/Blogger/Member/home.jsf

i have set transport-gaurantee for Admin folder and Member folder to NONE.

Any idea why is this happening and how should i resolve this?
