-PHP 8 on Azure App Service Linux use NGINX as the Web Server. To have NGINX route requests to `/public` we'll have to configure a custom startup script. We can grab the existing `default.conf` under `/etc/nginx/sites-available/default.conf` and run `cp /etc/nginx/sites-available/default.conf /home`. This will copy the `default.conf` we need into `/home` so we can download it with an FTP client or any other tool that allows this.

+- For **Static Javascript applications/SPA's** being hosted on a Linux App Service - like Angular, React, Vue, etc. - either something such as an AppGateway would need to be placed in front of the application, ran ontop of a Node server, a custom Docker Image (bringing your own Web Server to serve the static files), or [served through a Web Server on a PHP Blessed Image](https://azureossd.github.io/2022/05/18/Serving-SPAs-with-PHP-Blessed-Images/index.html) to accomplish this. 
+
+This is because SPA's are typically client-side code, executed in the browser, and have no notation of anything server side - **which means they can't change headers without additional configuration.** This concept is nothing Azure specific, but rather programmatic in general.

     If you'd rather add or change response headers through here, a custom startup script would need to be used. This can be done following either of this blog posts:
     1. [PHP Custom Startup Script - App Service Linux - Apache](https://azureossd.github.io/2020/01/23/php-custom-startup-script-app-service-linux/index.html) - this post also includes a way to include headers into Apache.

 - For **Tomcat containers** - bringing your own `web.xml` or [custom Tomcat Installation](https://azureossd.github.io/2022/05/20/Custom-Tomcat-Configuration-on-Azure-App-Service-Linux/index.html) may need to be done to do this through the Web Server itself. Embedded Tomcat in Spring Boot applications would be able to do this without the need for a custom installation.
