HTTP Status Codes

 

HTTP Status Codes are like messages from the website to your browser, telling you how the request went.

Q1. What is HTTPS?
Answer: HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP. It uses SSL/TLS to encrypt communication between the client and server, ensuring confidentiality, integrity, and authentication.

Q2. What is the default port for HTTPS?
Answer: 443.

Q3. Why is HTTPS more secure than HTTP?
Answer: Because it encrypts data in transit, verifies the server's identity using digital certificates, and protects against eavesdropping and tampering.

Q4. What happens if an SSL/TLS certificate is invalid or expired?
Answer: Browsers typically display a security warning, and users should avoid proceeding unless they trust the source.

Q5. Which status code indicates a successful HTTPS request?
Answer: 200 OK (although other 2xx codes like 201 and 204 also indicate successful outcomes depending on the operation).

1. 1xx - Informational : Preliminary status codes indicating the server has received the request and is continuing the process.

2. 2xx - Success : These codes mean the request was successful, showing various outcomes like:
- 200 OK : Everything went smoothly, and the server processed the request successfully.
- 201 Created : A new resource has been successfully created.

3. 3xx - Redirection : Signifying that more action is needed to complete the request, like:
- 301 Moved Permanently : The requested resource has been permanently moved elsewhere.

4. 4xx - Client Error : These codes represent errors caused by the client's request, including:
- 400 Bad Request : The server can't understand the request due to a client error.
- 404 Not Found : The requested resource doesn't exist on the server.

5. 5xx - Server Error : Indicating issues on the server side, such as:
- 500 Internal Server Error : Something unexpected happened on the server, causing an error.
