Reverse proxy and load balancer NOT supported

Environment

Windows, URLRewrite, IIS

Issues

After checked the source code, The following files should be changed. I have verified the changes and it worked well in my environment.
AddBaGetWebApplication method in IServiceCollectionExtensions.cs
` public static IServiceCollection AddBaGetWebApplication(
this IServiceCollection services,
Action configureAction)
{
services
.AddRouting(options => options.LowercaseUrls = true)
.AddControllers()
.AddApplicationPart(typeof(PackageContentController).Assembly)
.SetCompatibilityVersion(CompatibilityVersion.Version_3_0)
.AddJsonOptions(options =>
{
options.JsonSerializerOptions.IgnoreNullValues = true;
});
// Enable reverse proxy and load balancer support
services.Configure(options =>
{
options.ForwardedHeaders = ForwardedHeaders.All;
});

        services.AddRazorPages();

        services.AddHttpContextAccessor();
        services.AddTransient<IUrlGenerator, BaGetUrlGenerator>();

        services.AddBaGetApplication(configureAction);

        return services;
    }`

AbsoluteUrl method in BaGetUrlGenerator.cs

` private string AbsoluteUrl(string relativePath)
{
var request = _httpContextAccessor.HttpContext.Request;

        string forwardedHost = request.Headers["HTTP_X-Forwarded-Host"];
        var proto = request.Headers["HTTP_X-Forwarded-Proto"].FirstOrDefault()??"https";
        if(!string.IsNullOrEmpty(forwardedHost))
        {
            return proto+"://"+forwardedHost + request.PathBase.ToUriComponent() + "/" + relativePath;
        }

        return string.Concat(
            request.Scheme,
            "://",
            request.Host.ToUriComponent(),
            request.PathBase.ToUriComponent(),
            "/",
            relativePath);
    }`
