    0To ensure your ABP Framework MVC Core multi-layer website defaults to Arabic (or any language) when opened in a new incognito window, you need to configure the default culture and ensure the localization middleware is set up correctly. By default, ABP uses the browser's language or falls back to English if no preference is found. Solution Steps: - Set the Default Culture in Startup: In your - Startup.cs(or the module's- ConfigureServices), configure the- RequestLocalizationOptionsto set Arabic as the default culture:
 services.Configure 2. **Ensure Middleware Order:** In your `OnApplicationInitialization` or `Configure` method, make sure `UseRequestLocalization()` is called before `UseRouting()`: ```csharp app.UseRequestLocalization(); app.UseRouting(); // ... other middleware- Check for URL-Based Localization (Optional but Recommended): For SEO and user experience, consider using URL-based localization (e.g., - /ar/home). This ensures the language is explicit in the URL and not just based on cookies or browser settings. You can implement this using custom routing and middleware as described in the ABP community article:- Add a route parameter for language.
- Use a custom RouteDataRequestCultureProviderto extract the culture from the URL.
- Optionally, use a TagHelper to ensure all links include the language code.
 - See the full working sample and implementation details here: 
- Clear Browser Cache/Cookies: Incognito windows do not retain cookies or local storage, so the default language will be used unless the language is specified in the URL or detected from the browser. 
- Verify Language Switcher: If you have a language switcher, ensure it sets the culture in the URL or via a cookie, and that your localization middleware respects this. 
 By following these steps, your website will default to Arabic for new users and in incognito windows, unless another language is explicitly selected. Sources: - ABP Community Article: URL-Based Localization

    0hi What is your UI page? MVC, Angular, or Blazor? There is an AcceptLanguageHeaderRequestCultureProvider(accept-language )by default.It will use your browser language instead of your default language. https://learn.microsoft.com/en-us/aspnet/core/fundamentals/localization/select-language-culture?view=aspnetcore-9.0#configure-localization-middleware Can you check the accept-languagevalue in your browser?Thanks.
