Hi,

Our site has few secure pages (updatepassword.aspx and checkout.aspx ...)
if user request nonsecure with https then we should do the redirect like below.

https to http
https://www.companyurl.aspx/default.aspx needs to redirect to http://www.companyurl.aspx/default.aspx

http to https
http://www.companyurl.aspx/updatepassword.aspx needs to redirect to https://www.companyurl.aspx/updatepassword.aspx


how do i write the redirect url for this request?
