👇 What is the difference between a GET and a POST request ❓ A GET request retrieves data from a server, whereas a POST sends data to a server. With a GET request, parameters get passed in the URL. With a POST request, parameters get passed in the request's body.

What are HTTP Status codes in REST ? These are the standard codes that refer to the predefined status of the task at the server. Following are the status codes formats available: 1xx - represents informational responses 2xx - represents successful responses 3xx - represents redirects 4xx - represents client errors 5xx - represents server errors Most commonly used status codes are: 200 - success/OK 201 - CREATED - used in POST or PUT methods. 304 - NOT MODIFIED - used in conditional GET requests to reduce the bandwidth use of the network. Here, the body of the response sent should be empty. 400 - BAD REQUEST - This can be due to validation errors or missing input data. 403 - FORBIDDEN - sent when the user does not have access (or is forbidden) to the resource. 404 - NOT FOUND - Resource method is not available. 500 - INTERNAL SERVER ERROR - server threw some exceptions while running the method. 502 - BAD GATEWAY - Server was not able to get the response from another upstream server.

#WebWednesday HTTP Status Codes Cheat Sheet 1XX — Informational codes: The server acknowledges and is processing the request. 2XX — Success codes: The server successfully received, understood, and processed the request. 3XX — Redirection codes: The server received the request, but there’s a redirect to somewhere else (or, in rare cases, some additional action other than a redirect must be completed).  4XX — Client error codes: The server couldn’t find (or reach) the page or website. This is an error on the site’s side.  5XX — Server error codes: The client made a valid request, but the server failed to complete the request. 

Although most people only use GET, POST, PUT, and DELETE when working with HTTP, there are actually 39 different actions, or "verbs", in the official list. In this post, we'll look at 9 of the most popular ones. 1️⃣ GET Method: Gets data from a server. 2️⃣ POST Method: Sends data to a server to create something new. 3️⃣ PUT Method: Changes something that's already on a server. 4️⃣ PATCH Method: Changes part of something on a server. 5️⃣ DELETE Method: Removes something from a server. 6️⃣ HEAD Method: Gets information about something on a server. 7️⃣ OPTIONS Method: Tells you how you can interact with something on a server. 8️⃣ TRACE Method: Shows the path of communication between you and the server. 9️⃣ CONNECT Method: Makes a special kind of connection to a server.

HTTP status codes are three-digit numbers that indicate the outcome of a client's request to a server. They are grouped into five classes: 1. Informational responses (100–199): These codes indicate that the request was received and understood. For example: - **100 Continue**: The server has received the request headers and the client should proceed to send the request body. 2. Successful responses (200–299): These codes indicate that the request was successfully received, understood, and accepted. For example: - **200 OK**: The request succeeded, and the requested resource is being sent in the response. 3. Redirection messages (300–399): These codes indicate that further action needs to be taken to complete the request. For example: - **301 Moved Permanently**: The requested resource has been permanently moved to a new URL. 4. Client error responses (400–499): These codes indicate that there was an error with the request. For example: - **404 Not Found**: The requested resource could not be found on the server. 5. Server error responses (500–599): These codes indicate that the server failed to fulfill a valid request. For example: - **500 Internal Server Error**: The server encountered an unexpected condition that prevented it from fulfilling the request.

Here's a concise description of some important HTTP status codes: 200 OK: "Success! The server successfully processed the request and returned the requested information." 201 Created: "Resource created! The request has been fulfilled, resulting in the creation of a new resource." 204 No Content: "No content to return. The server successfully processed the request, but there is no information to send back." 400 Bad Request: "Oops! The server couldn't understand the request due to invalid syntax or other client-side errors." 401 Unauthorized: "Access denied! The request requires user authentication, and the credentials provided are not valid." 403 Forbidden: "Permission denied! The server understood the request, but the client does not have the necessary permission." 404 Not Found: "Not here! The requested resource could not be found on the server." 500 Internal Server Error: "Something went wrong! A generic error message indicating a server-side problem preventing the request from being fulfilled." 502 Bad Gateway: "Gateway issue! The server, while acting as a gateway or proxy, received an invalid response from an upstream server." 503 Service Unavailable: "Temporarily unavailable! The server is not ready to handle the request due to temporary overloading or maintenance."

Now you can encrypt data with transferToClient and decrypt it automatically on the server. Useful for this type of transfer: server render → client → server action → client Although it should be the last option. We recommend that you do not transfer sensitive data and do not need to encrypt it, and it is OK if the action does more work by re-requesting the data. Note: The server store only lives at request time so that any server component can access the store unless you use transferToClient, which extends the life of the store.

The three-way handshake in TCP is a crucial process that establishes a reliable connection between a client and a server. It's called a three-way handshake because it involves three steps: 1. The client sends a SYN (synchronize) packet to the server to initiate the connection. 2. The server responds with a SYN-ACK (synchronize-acknowledge) packet, acknowledging the client's request and asking for synchronization. 3. The client sends an ACK (acknowledge) packet back to the server, confirming the connection. This process ensures that both parties are ready to communicate and agree on initial sequence numbers, which helps in reliable data transmission and proper packet ordering.
