Reverse proxies on IIS

[Wessel, Keith]

Hi, all,

We have a vendor running a site on IIS. They recently moved it behind a load balancer that's also handling the https component; the server is seeing http instead of https.

I had them set handlerSSL to false and cookieProps to http, and we're closer. But now the IdP is requesting the authn request because the endpoint URL has an http scheme instead of https.

I know this can be fixed in Apache by setting the canonical name to include the scheme and port instead of just a hostname. Can anyone tell me how to accomplish this in IIS? I, obviously, want the return endpoint URL to have an https scheme even though the server is seeing the request as http.

Thanks,
Keith
