🔍 How a User Request Travels from the Browser to the Web Server and Back

Have you ever wondered what's going on behind the scenes when you type something into your browser and press Enter? How does your screen instantly load the exact info you're looking for?

Let's break down, in simple steps, how a user's request travels-from your browser to a server and back-delivering a complete web page.

🧭 Step 1: User Types a Query
It all begins when you enter a URL or search term into a browser.

🌐 Step 2: Browser Sends a GET Request
The browser sends a GET request to a search engine, which crawls the web and returns relevant links.

🌍 Step 3: DNS Lookup
To visit a website (like LinkedIn), your browser resolves its domain to an IP address using DNS.

🖥️ Step 4: Connect to the Web Server
Now that the browser knows where to go, it connects to the server that hosts the site.

🔐 Step 5: Secure Connection (HTTPS)
A secure connection is established via TLS/SSL, ensuring privacy and security.

📝 Step 6: Static Content Served
If it's a static page, the server sends HTML, CSS, and JS directly to the browser.

📄 Step 7: DOM Creation
The browser parses HTML and CSS to build a DOM tree and render structure.

📐 Step 8: Layout & Paint
The browser calculates the layout and paints each element onto the screen.

👀 Step 9: Static Page Displayed
The user now sees a complete static page-but it's not interactive yet.

🔁 Step 10: Request for Dynamic Content
When interaction is needed (e.g., filtering jobs), the browser makes a new request.

🧠 Step 11: Backend & Database Logic
The server processes this via backend logic and databases, returning personalized content.

💻 Step 12: Browser Renders Dynamic Page
JavaScript runs, the DOM updates, and now the user gets a fully interactive experience.

💡 Final Thought
Every click kicks off a complex yet beautifully orchestrated dance between your browser, servers, and code-all working together to bring you the web in seconds
