You copy the link again and paste it in URL and it opens fine? This is an effect of CORS or cross origin resource sharing. https://husseinnasser.com/courses

You can also extend the server capability by writing your own extensions. In this episode ArcGIS Server talk we will talk about two ways you can extend your ArcGIS server, Server Object Extensions and Server Object Interceptors. Server Object Extension Extends the MapServer to allow you to wr...

Any content served through HTTP “should” include meta data about its type. This is so the browser/client knows what to do with the content it receives. For example, if the content type header is an image the browser will preview it, if it is HTML it will render the markup and execute any javascript code. Content type however is optional and web masters sometimes don’t set it, which leave the browsers wondering about the content type it is consuming. So browsers had to implement parsing and “snif...

Sde intercept Any operation performed on ArcGIS ends up eventually to the geodatabase as a set of one or more queries. A “zoom-in” or pan operation translates to multiple queries to the underlying geodatabase. SDE intercepts always you to intercept and take a look at those queries to diagnose slow operations in your enterprise geodatabase. It also helps pinpoint where the bottle neck is and how can you optimize your app or geodatabase. https://support.esri.com/en/technical-article/000010355

Most of the time a Load balancer is a reverse proxy but a reverse proxy is not necessary a load balancer. Reverse proxy takes a request from client and forward it to “a server” doesn’t care of the server is overloaded or down or not just forwards it. Load balancer stores state about each server behind it, how overloaded each server is, and what server is down, and smartly forward request to a server to balance the load across all the group. So a load balancer is a special case of a reverse proxy...
