  To achieve your goal of exposing multiple ABP services (Host, Auth, Web) under a single domain and port using a reverse proxy, you need to ensure that:

  1. Each backend service is configured to work behind a reverse proxy.
  2. Path-based routing is set up in your reverse proxy (e.g., IIS, Nginx, or YARP).
  3. Forwarded headers are correctly handled in your ABP applications.

  Key Steps

  1. Configure Forwarded Headers Middleware

  In each ABP application's Startup.cs (or Program.cs for .NET 6+), add the Forwarded Headers Middleware at the top of the middleware pipeline:

  app.UseForwardedHeaders(new ForwardedHeadersOptions
  {
      ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
  });
  

  This ensures the application correctly interprets the original request's scheme and host.

  2. Reverse Proxy Path Mapping

  Configure your reverse proxy to map paths as follows:

  • /api → Host Server (https://localhost:44342)
  • /auth → Auth Server (https://localhost:44339)
  • / → Web Server (https://localhost:44378)

  For example, in IIS, you can use URL Rewrite rules or in YARP (Yet Another Reverse Proxy) you can define routes in appsettings.json.

  3. Update ABP Configuration

  • Set App:SelfUrl, AuthServer:Authority, and RemoteServices:Default:BaseUrl in each app's appsettings.json to use the public-facing URL (https://localhost:44378).
  • Ensure CORS and redirect URIs are set to the single domain.

  4. Test and Debug

  • Make sure all static files, cookies, and authentication flows work as expected.
  • If you encounter issues with authentication or redirects, double-check the forwarded headers and public URLs.

  Reference

  • ABP Forwarded Headers Middleware

  This approach is required for correct operation behind a reverse proxy, especially for authentication and URL generation.
