When a user enters a website URL in a web browser, the web browser makes a request to the web server that hosts the website. This request is typically initiated using the Hypertext Transfer Protocol (HTTP) or its secure variant, HTTPS (HTTP over SSL/TLS). Here's a general overview of the process:
- URL Parsing: The web browser parses the entered URL to extract the components, such as the protocol (HTTP/HTTPS), domain name (e.g., example.com), and any additional path or query parameters.
- DNS Resolution: The browser performs a DNS lookup to translate the domain name into the corresponding IP address of the web server. It sends a DNS query to a DNS resolver, which recursively resolves the domain name and provides the IP address.
- Establishing a Connection: Once the IP address is obtained, the browser establishes a TCP/IP connection with the web server using the IP address and the default port number for the selected protocol (80 for HTTP, 443 for HTTPS).
- Sending the Request: The browser sends an HTTP/HTTPS request to the web server. This request includes the desired resource (specified in the URL), optional headers, and other relevant information. For example, a request for the homepage of a website might be a GET request like:
vbnetCopy code
GET / HTTP/1.1
Host: example.com - Server Processing: The web server receives the request and processes it. It retrieves the requested resource or performs the necessary server-side operations.
- Sending the Response: The web server generates an HTTP response containing the requested resource or the appropriate status/error codes. The response is sent back to the web browser over the established connection.
- Rendering the Page: The web browser receives the response and interprets the HTML, CSS, JavaScript, and other resources to render the web page. It may issue subsequent requests for additional resources (e.g., images, scripts, stylesheets) referenced within the HTML.
- Displaying the Page: The web browser displays the rendered web page to the user, who can interact with it and view its content.

When a user enters a website URL into a web browser, the browser makes a request to the web server associated with that URL. The request is typically made over the Hypertext Transfer Protocol (HTTP) or its secure variant, HTTPS (HTTP over SSL/TLS).
Here's a simplified overview of the process:
Here's a simplified overview of the process:
- URL Parsing: The web browser parses the URL entered by the user to extract the various components, including the protocol (HTTP or HTTPS), domain name (e.g., example.com), and any additional path or query parameters.
- DNS Resolution: If the browser does not have the IP address of the web server already cached, it initiates a DNS lookup to resolve the domain name to its corresponding IP address. The DNS resolution process, as described earlier, involves contacting DNS resolvers and authoritative name servers to obtain the IP address.
- Establishing a Connection: Once the browser has obtained the IP address, it establishes a connection with the web server using the appropriate protocol (HTTP or HTTPS) and the designated port (usually port 80 for HTTP and port 443 for HTTPS).
- Sending the Request: The web browser crafts an HTTP request based on the parsed URL, including the requested resource (such as a specific webpage or file), HTTP headers, and any additional data. The request is then sent to the web server over the established connection.
- Server Processing: The web server receives the request and processes it. This typically involves handling the HTTP headers, parsing the requested resource, executing any server-side scripts or programs, accessing databases or files, and generating a response.
- Server Response: After processing the request, the web server generates an HTTP response containing the requested resource or appropriate status codes (e.g., 200 for success, 404 for not found). The response may also include additional headers, cookies, and other data.
- Receiving and Rendering: The web browser receives the server's response and interprets it. It may handle various content types, such as HTML, CSS, JavaScript, images, or videos. The browser then renders the content, displaying the webpage or executing any associated scripts.

When a user enters a website URL into a web browser, the web browser makes a request to the web server hosting that website. The web server is the computer or system that stores the website's files and delivers them to the requesting browser.
The request made by the web browser is typically an HTTP (Hypertext Transfer Protocol) or HTTPS (HTTP Secure) request. It includes the URL of the website or specific page being accessed.
Once the request is received by the web server, it processes the request and retrieves the requested files associated with the URL. This may involve accessing databases, running server-side scripts, or retrieving static files from the server's file system.
The web server then sends a response back to the browser, which contains the requested files or relevant data. The response is usually in the form of HTML, CSS, JavaScript, images, or other resources required to render the web page.
The browser receives the response and interprets the received data to display the website content to the user. This includes rendering the HTML structure, applying CSS styles, executing JavaScript code, and displaying any media elements.
In summary, when a user enters a website URL, the web browser makes a request to the web server hosting that website to retrieve the necessary files and content to display the webpage in the browser.

When a user enters a website URL (Uniform Resource Locator) in a web browser, the web browser makes a request to the web server associated with that URL. The web server is responsible for hosting the website and delivering the requested web pages and resources to the user's browser. The request is typically made using the HTTP (Hypertext Transfer Protocol) or HTTPS (HTTP Secure) protocols, depending on whether the website uses a secure connection.
The web browser sends an HTTP request to the web server, specifying the URL of the website and the specific resource or page being requested. This request includes a method (such as GET or POST) that indicates the desired action, headers that provide additional information about the request, and any necessary data or parameters.
Upon receiving the request, the web server processes it and determines the appropriate response. It retrieves the requested resource, such as an HTML file, image, CSS stylesheet, or JavaScript file, from its storage or generates it dynamically. The web server then constructs an HTTP response containing the requested resource, appropriate status codes (e.g., 200 for a successful response), headers, and other relevant information.
The web server sends the HTTP response back to the user's web browser, which interprets the response and renders the web page or resource accordingly. The web browser processes the HTML, executes any embedded scripts or stylesheets, and displays the final rendered webpage to the user.
This entire process of the web browser making a request to the web server and receiving a response is fundamental to how websites are accessed and displayed in a user's web browser. It enables the seamless retrieval and presentation of web content over the internet.
