Hi Theodor

>>I've tried with the standard way in a .net application, but it doesnt seem to work

You can do that when you take over the program.cs - which requires you to host Dynamicweb your self as that is not supported in the cloud. Be aware that cors has to be registered very early - otherwise it will not work.

Dynamicweb supports iPipeline for adding stuff to the pipeline using custom addins - see this one: https://doc.dynamicweb.dev/documentation/extending/middleware/index.html

using Dynamicweb.Host.Core;
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;

namespace CustomCode;

public class CorsPipeline : IPipeline
{
    public int Rank => -1; // Ensure CORS runs early enough

    private const string CorsPolicyName = "DefaultCors";

    public void RegisterServices(IServiceCollection services, IMvcCoreBuilder mvcBuilder)
    {
        services.AddCors(options =>
        {
            options.AddPolicy(CorsPolicyName, policy =>
            {
                policy.WithOrigins(
                        "https://www.dynamicweb.dk",
                        "https://partner.yourdomain.com")
                      .AllowAnyHeader()
                      .AllowAnyMethod();
            });
        });
    }

    public void RegisterApplicationComponents(IApplicationBuilder app)
    {
        app.UseCors(CorsPolicyName);
    }

    public void RunInitializers()
    {
        // No initializers needed for CORS
    }
}

I believe this should work - but have not tested it. It might not be early enough in the pipeline....

Good luck getting the headers correct :-).
