Part 5/10:
With the connection secure, the browser sends an HTTP GET request to the server, asking for the HTML content of the web page. This request contains headers that provide metadata, helping the server understand how to process it correctly. Among these headers is the user-agent string, which allows the server to optimize its response based on the capabilities of the requesting browser.
Once the server receives the request, it directs it to the appropriate web service, which could involve consulting databases or running server-side scripts to dynamically generate a personalized response if required.
