1. 2xx Success Codes – The Request Was Successful
These codes mean that everything went well, and the server successfully responded to your request.
- 200 OK: This is the best code to get! It means that the request was successful, and the server sent back the webpage or data you wanted.
- 201 Created: The request was successful, and as a result, something new was created. For example, this might happen when you sign up for a new account on a website.
- 202 Accepted: The request has been accepted, but it hasn’t been fully processed yet. The server is working on it and will complete it later.
2. 3xx Redirection Codes – The Request Was Redirected
These codes tell you that the requested page has moved somewhere else or that you need to take further action to complete the request.
- 301 Moved Permanently: The page you requested has been moved to a new location, and it’s there permanently. You won’t find the old page anymore; it has a new URL.
- 302 Found (Temporary Redirect): The page is still available, but it’s temporarily moved to another location. You might be sent to the new location for now, but it’s not permanent.
- 304 Not Modified: The webpage hasn’t changed since the last time you visited it. The server is telling your browser, “You already have the most recent version, no need to download it again.”
3. 4xx Client Error Codes – There’s a Problem With Your Request
These codes indicate that the problem is on your end (the client), usually due to a bad request or missing permission to access something.
- 400 Bad Request: This means the server didn’t understand your request because it was malformed or incorrect. It’s like sending a garbled message that the server can’t process.
- 401 Unauthorized: You tried to access something that requires a login or authentication, but you didn’t provide valid credentials. You need to log in first to see this page.
- 403 Forbidden: You don’t have permission to access this resource, even if you’re logged in. The server knows who you are but is blocking you from accessing this page.
- 404 Not Found: This is one of the most common errors. It means the page you’re looking for doesn’t exist on the server. You might have mistyped the URL, or the page has been removed.
- 405 Method Not Allowed: The method you used to request the page (like GET or POST) is not allowed. For example, you might be trying to update something using a method that’s only allowed for viewing data.
- 408 Request Timeout: The server took too long to respond to your request. Maybe your internet connection was slow, or the server was overloaded.
4. 5xx Server Error Codes – The Server Has a Problem
These codes mean that something went wrong on the server’s side, not yours.
- 500 Internal Server Error: This is a generic error message that means something went wrong on the server, but the server doesn’t know exactly what caused it. It’s like the server saying, “I messed up, but I don’t know why.”
- 501 Not Implemented: The server can’t handle the request. For example, you might be asking the server to perform an action it’s not programmed to do.
- 502 Bad Gateway: The server, acting as a gateway or proxy, received an invalid response from another server. This usually happens when there’s a communication problem between servers.
- 504 Gateway Timeout: Similar to 408 (Request Timeout), but this happens between servers. The server you’re contacting didn’t get a timely response from another server it was relying on.
How to Deal with These Errors
- 2xx codes mean everything is good. No action is needed.
- 3xx codes mean the page has moved, and your browser should automatically take you to the new page.
- 4xx codes mean you need to check your request. Make sure you typed the URL correctly, and if it’s a login page, check your username and password.
- 5xx codes mean there’s nothing you can do; the problem is on the server’s end. Try again later or contact the website owner if it’s a frequent issue.
So after reviewing all HTTP status code, you can understand what is this, when any type of code occurs now you can understand what is this.
