Redirects

As for redirects, our browser reached this domain in two steps. The first redirect led to https://portal.keio.jp/koid/, then it was forwarded to https://auth.keio.jp/idp/profile/SAML2/Redirect/SSO?SAMLRequest=fZLLUsIwFIZfpZM9..., and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.
