Umbraco 13 Load balancing ssl offload force HTTPS

Questions

Hey

How do I use the “UseHttps": true” in the appsettings, in a setup where the ssl are not handled by the servers ? :slight_smile:

Any suggenstions for that?

Hey Thomashdk :slightly_smiling_face:

You need to configure forwarded headers and a known proxy/proxies.

This is how I’ve done it on my personal project, which is behind a Traefik proxy:

// Forward headers needed to pass information from the reverse proxy to the application
builder.Services.Configure<ForwardedHeadersOptions>(options =>
{
    options.ForwardedHeaders =
        ForwardedHeaders.XForwardedFor |
        ForwardedHeaders.XForwardedProto |
        ForwardedHeaders.XForwardedHost;

    options.KnownNetworks.Add(new IPNetwork(IPAddress.Parse("172.28.0.0"), 16));
});

// This is needed to forward the headers from the reverse proxy to the application
app.UseForwardedHeaders();
