#Http 502 Error

Because HTTP success ≠ business success. 200 OK only means: 👉 The request was received and processed correctly at the protocol level Not that the operation succeeded logically. Common reasons: 1. Business errors live in the response body Example: { "success": false, "error": "INSUFFICIENT_BALANCE" } Transport = success Business = failure 2. Client-side simplicity Some systems always return 200 to simplify client logic → error handling happens via response codes inside JSON 3. Legacy API patterns Older systems didn’t follow strict REST semantics 4. Idempotency & retries Returning non-200 can trigger automatic retries → causing duplicate operations If a payment fails logically, returning 500 may trigger retries → double charges. 200 + error message avoids dangerous retries. 5. Bad design (yes, sometimes) Some teams misuse 200 to hide bad API design or monitoring gaps. 🧠 Reality Rule: HTTP codes describe network/transport state Application logic describes business state The server worked. The business logic didn’t.#systemdesigninterview #coding #code #google #ai

HTTP vs HTTPS: The Real Reason 🔐 --- In interviews, we often say “HTTPS is secure, HTTP is not” — but the real reason is rarely explained properly. In HTTP, data travels as plain text, which means anyone in between (like attackers or intermediaries) can read or intercept the packets. In HTTPS, data is protected using TLS encryption. TLS encrypts the communication between the client and the server, so even if someone captures the packets, they can’t understand the data. This video explains: • Why HTTP is insecure • How plain-text data can be read in transit • How TLS encryption makes HTTPS secure If you’re a developer, student, or preparing for interviews, this is the explanation you should actually give.
