Using Login In on Default page Http/Https

My website Introduces users to site via a default pages (http://domainName/Default.aspx) contained on page is user Login Control.  Upon user authentication user is transfer to a role driven admin page or a member page (https://domainName/siteName/RoleDrivenPage.aspx).  My problem is everyone needs access to see Default page because there are links to non-secure areas.  I cannot set 'requireSSL= true' because default page resides on 'http', and when I set 'requireSSL=false' user logs in and then require to login again using https://domainName/siteName/Default.aspx.  

Is there a way to use this Default/Login functionality?
