Every click on a website triggers a chain of events that happen in milliseconds. Here's a simplified breakdown of how a request travels:

1. The Click

When you click, your browser creates an HTTP request with details like the URL, method (e.g., GET, POST), and any extra data.

2. DNS Lookup

The browser finds the server's IP address by checking its cache or querying a DNS server.

3. Connection Setup

The browser and server set up a secure connection using TCP and TLS (for HTTPS).

4. Server Handling

The request reaches the server, possibly passing through load balancers or firewalls. The server processes it, runs business logic, and interacts with the database if needed.

5. Response Generation

The server creates a response with a status code (like 200 OK) and the data or HTML needed.

6. Back to Browser

The response travels back to the browser, which renders the page and runs any JavaScript for dynamic features.

This quick journey happens for every action you take online, ensuring seamless interactions. Behind the scenes, it’s a blend of speed, efficiency, and teamwork between technologies.
