The Flow of the Web Application

In general, a user sends a request to the web-server using web browsers such as Google Chrome, Microsoft Edge, Firefox, etc over the internet.

Then, the request is forwarded to the appropriate web application server by the web-server.

Web application server performs the requested operations/ tasks like processing the database, querying the databases; produces the result of the requested data.

The obtained result is sent to the web-server by the web application server along with the requested data/information or processed data.

The web server responds to the user with the requested or processed data/information and provides the result to the user's screen.
