Some useful status code that every developer should know Common HTTP Status Codes Status Code 200 – This is the standard “OK” status code for a successful HTTP request. The response that is returned is dependent on the request. For example, for a GET request, the response will be included in the message body. For a PUT/POST request, the response will include the resource that contains the result of the action. Status Code 201 – This is the status code that confirms that the request was successful and, as a result, a new resource was created. Typically, this is the status code that is sent after a POST/PUT request. Status Code 204 – This status code confirms that the server has fulfilled the request but does not need to return information. Examples of this status code include delete requests or if a request was sent via a form and the response should not cause the form to be refreshed or for a new page to load. Status Code 304 – The is status code used for browser caching. If the response has not been modified, the client/user can continue to use the same response/cached version. For example, a browser can request if a resource has been modified since a specific time. If it hasn’t, the status code 304 is sent. If it has been modified, a status code 200 is sent, along with the resource. Status Code 400 – The server cannot understand and process a request due to a client error. Missing data, domain validation, and invalid formatting are some examples that cause the status code 400 to be sent. Status Code 401 – This status code request occurs when authentication is required but has failed or not been provided. Status Code 403 – Very similar to status code 401, a status code 403 happens when a valid request was sent, but the server refuses to accept it. This happens if a client/user requires the necessary permission or they may need an account to access the resource. Unlike a status code 401, authentication will not apply here. Status Code 404 – The most common status code the average user will see. A status code 404 occurs when the request is valid, but the resource cannot be found on the server. Even though these are grouped in the Client Errors “bucket,” they are often due to improper URL redirection. Status Code 409 – A status code 409 is sent when a request conflicts with the current state of the resource. This is usually an issue with simultaneous updates, or versions, that conflict with one another. Status Code 410 – Resource requested is no longer available and will not be available again. Learn about network error 410. Status Code 500 – Another one of the more commonly seen status codes by users, the 500 series codes are similar to the 400 series codes in that they are true error codes. The status code 500 happens when the server cannot fulfill a request due to an unexpected issue. Web developers typically have to comb through the server logs to determine where the exact issue is coming from.

💻 Key Contents of HTTP Response Headers 🌐 HTTP response headers provide important metadata about the response sent from a server to a client (usually a browser). These headers contain crucial information that helps browsers interpret and display the requested data. Here's a breakdown of some key HTTP response headers and their significance: 1️⃣ Status Code: Indicates the result of the request (e.g., 200 OK, 404 Not Found, 500 Internal Server Error). It tells the client whether the request was successful or if there was an error. 2️⃣ Content-Type: Specifies the media type (e.g., text/html, application/json) of the returned resource, helping the browser understand how to process the content. 3️⃣ Content-Length: Indicates the size of the response body in bytes. This helps the client understand how much data it should expect to receive. 4️⃣ Cache-Control: Controls how the response is cached by browsers or intermediary proxies. It can prevent caching or set expiration times for cacheable responses (e.g., Cache-Control: no-cache). 5️⃣ Set-Cookie: Sends cookies from the server to the client. Cookies store session data and are used to maintain state between requests (e.g., Set-Cookie: sessionId=abc123; Path=/; HttpOnly). 6️⃣ Location: Used with 3xx status codes to indicate a redirection to a new URL. It tells the client where to navigate if the resource has been moved. 7️⃣ Server: Provides information about the server software handling the request (e.g., Server: Apache/2.4.41). While informative, it can also be a security concern as it reveals details about the server. 8️⃣ Expires: Indicates when the resource will expire and no longer be considered fresh. This is used to manage cache duration for client-side performance. 9️⃣ Content-Encoding: Specifies any encoding transformations applied to the content, such as gzip, deflate, or br. It helps in reducing the size of the transmitted data. 🔟 Access-Control-Allow-Origin: Used in CORS (Cross-Origin Resource Sharing) to specify which domains are allowed to access the resource. Helps secure APIs by controlling cross-origin requests. Understanding HTTP response headers is crucial for web developers to optimize performance, enhance security, and provide a seamless user experience! 🌐 #WebDevelopment #HTTP #APIs #ServerResponse #HTTPHeaders #WebPerformance #SoftwareEngineering #Networking #TechSkills #WebSecurity #DeveloperLife #TechCommunity #BackendDevelopment #LinkedInLearning

What happens you type https://www.google.com in your browser and press Enter? Have you ever wondered what happens in the blink of an eye when you type a web address and press Enter? It might seem like magic, but there's a fascinating sequence of events that goes down behind the scenes. Today, we'll delve into the exciting world of web technologies and explore what unfolds when you request that familiar address: https://www.google.com. The DNS Mystery: Translating Words to Numbers Our journey begins with a concept called the Domain Name System (DNS). Imagine it as the internet's phonebook. When you type "google.com," your browser doesn't understand this human-readable address. It needs a numerical equivalent, like a phone number, to locate Google's servers. So, the browser sends a request to a DNS server, asking, "What's the IP address for google.com?" Handshake Time: Connecting with the Server Armed with the IP address, your browser initiates a connection with Google's server. This connection relies on a set of protocols called TCP/IP, which acts like a language computers use to communicate. Imagine it as a digital handshake establishing a secure channel for data exchange. Security First: The Importance of HTTPS You might have noticed the "https" at the beginning of the URL. This stands for Hypertext Transfer Protocol Secure, the encrypted version of HTTP. When you see https, it means the communication between your browser and the server is scrambled, making it more difficult for eavesdroppers to intercept sensitive information. Behind the Curtain: The Server's Role Once the connection is established, your browser sends a request to the server, specifying what you're looking for (in this case, the Google homepage). The server then springs into action. It might retrieve content from its storage, consult databases, or even generate the webpage dynamically based on your preferences. Building the Page: A Collaborative Effort Modern webpages are often a complex mix of different elements like HTML, CSS, and JavaScript. The server might delegate tasks to different software programs to assemble the final webpage you see. Imagine a team effort, where each program contributes its expertise to build the complete picture. The Grand Finale: Rendering on Your Screen Finally, the server sends all the necessary data back to your browser. Your browser acts like a skilled interpreter, deciphering the code and assembling the visual elements – the text, images, and interactive features – to render the Google homepage on your screen. And Beyond: A Never-Ending Dance This is a simplified overview, but it captures the essence of what happens when you type a URL. There are many other players involved, like caching mechanisms for faster loading times, firewalls for security, and load balancers for distributing traffic across multiple servers. The web is a dynamic ecosystem, constantly evolving to provide a seamless user experience.

𝐓𝐨𝐩𝐢𝐜 : 𝐇𝐓𝐓𝐏 𝐨𝐫 𝐇𝐲𝐩𝐞𝐫𝐭𝐞𝐱𝐭 𝐓𝐫𝐚𝐧𝐬𝐟𝐞𝐫 𝐏𝐫𝐨𝐭𝐨𝐜𝐨𝐥, HTTP, or Hypertext Transfer Protocol, is the underlying protocol used for communication on the World Wide Web. It is a protocol that defines how messages are formatted and transmitted, and how web servers and browsers should respond to various commands. Here's a breakdown of some key aspects of HTTP: 1. 𝑹𝒆𝒒𝒖𝒆𝒔𝒕-𝑹𝒆𝒔𝒑𝒐𝒏𝒔𝒆 𝑴𝒐𝒅𝒆𝒍: A client, usually a web browser, sends a request to a server. The server then processes the request and sends back a response containing the requested information. 2. 𝑺𝒕𝒂𝒕𝒆𝒍𝒆𝒔𝒔 𝑷𝒓𝒐𝒕𝒐𝒄𝒐𝒍: HTTP is stateless, meaning each request from a client to a server is treated independently without any knowledge of previous requests. 3. 𝑴𝒆𝒕𝒉𝒐𝒅𝒔: HTTP defines several methods (also known as verbs) that specify the action to be performed on a resource. The most commonly used methods are: ⚫ 𝑮𝑬𝑻: Requests data from a specified resource. ⚫ 𝙋𝙊𝙎𝙏: Submits data to be processed to a specified resource. ⚫ 𝙋𝙐𝙏: Replace a resource. ⚫ 𝘿𝙀𝙇𝙀𝙏𝙀: Remove a resource. ⚫ 𝑯𝑬𝑨𝑫: No message body (response header only). ⚫ 𝑶𝑷𝑻𝑰𝑶𝑵𝑺: Returns the supported HTTP methods for a resource. ⚫ 𝑷𝑨𝑻𝑪𝑯: Change part of a resource. 4. 𝙐𝙍𝙇𝙨: Uniform Resource Locators (URLs) are used to identify resources on the web. They consist of a protocol (e.g., http or https), a domain name or IP address, and optionally a path to a specific resource on the server. 5. 𝙃𝙚𝙖𝙙𝙚𝙧𝙨: HTTP messages include headers, which provide additional information about the request or response. Headers can convey details such as content type, content length, caching directives, and more. 6. 𝙎𝙩𝙖𝙩𝙪𝙨 𝘾𝙤𝙙𝙚𝙨 : HTTP responses include status codes indicating the outcome of the request. Some common status codes include: ⚫ 1𝑿𝑿 : Informational ⚫ 2𝑿𝑿 : Success ⚫ 3𝑿𝑿 : Redirection ⚫ 4𝑿𝑿 : Client Error ⚫ 5𝑿𝑿 : Server Error Overall, HTTP is a foundational protocol for the World Wide Web, enabling the exchange of information between clients and servers, facilitating the retrieval and delivery of web resources. 🙏 Grateful for the Knowledge Shared by Hitesh Choudhary! 🌟 His clear explanations and hands-on approach have truly demystified this fundamental aspect of backend development for me.

How does the Web Work? Ever wondered what happens when you type a URL and hit enter? Let’s break down the key components and processes that allow the web to function smoothly. ### The Basics: What Happens When You Access a Website? When you enter a URL, the browser requests data from the server. The server responds with the website's code, which the browser displays.This is the request-response model or client-server architecture. Now let’s look at what the **client **and **server **are. - Client: This is your device (like your phone or computer) where you interact with the web. The browser acts as a client, requesting web pages and displaying them to you. - Server: A specialized computer that stores and manages data for websites. These servers are called such because they serve up code or data in response to requests made by clients. ### What is URL, and how does it get resolved A URL (Uniform Resource Locator) is the web address you type into your browser. URLs typically contain several parts, including a protocol, domain name, and path. - Protocol (HTTP/HTTPS): The method used to transfer data. - Domain name: The unique name of the website (like github.com). - Path: The specific page or resource (like github.com/about). - Optionally, the URL may also include a query string, a set of characters added to the end of the URL that contains additional information or parameters for the resource. When an URL is entered, the browser first sends a request to the DNS (Domain Name System) server, which matches the domain name to the corresponding IP address of the website. This is called DNS Lookup. This process is facilitated by your internet service provider and returns the IP address, including the port number of the server being accessed. ### How Data Travels: TCP/IP Protocols Once the server’s IP address is found, the browser establishes a TCP/IP connection: - TCP ensures reliable data transfer by breaking it into smaller chunks called packets. - IP handles routing these packets between devices. These two protocols ensure your data travels safely and reaches the right destination. ### Requesting Data with HTTP The browser sends an HTTP request to the server, asking for data (like a web page). Common methods are: #GET: Requesting data. #POST: Sending data (e.g., submitting a form). The server then sends an HTTP response, which includes the website’s data, status (success, error), and other details. ### Rendering the Web Page Once the browser receives the website’s code (usually HTML, CSS, and JavaScript): - It parses the HTML to understand the structure of the page. - It requests additional resources like images, CSS for styling, and JavaScript for functionality. - It renders the page, turning the code into what you see on the screen. ### Conclusion Understanding how the web works helps developers grasp the entire system, from sending requests to rendering a page. While there’s much more complexity, these basics give you a strong foundation.
