HTTP Status Codes: A Comprehensive Guide
HTTP status codes are the result of an HTTP request. They tell you whether everything went well or not. In this comprehensive guide, we will cover all HTTP status codes and what they mean for your website.
What are HTTP status codes?
HTTP status codes are a way of indicating the response of a request or server. They can be divided into 5 major categories:
- Informational responses (100 – 199)
- Successful responses (200 – 299)
- Redirection messages (300 – 399)
- Client error responses (400 – 499)
- Server error responses (500 – 599)
What do the different HTTP status codes mean?
The 5 most common HTTP status codes are:
1. 200 – This means that the request was successful and returned data in a format that can be used by the client
2. 404 – This means that the requested resource does not exist, but could mean other things as well such as when there is an error loading a page or trying to access protected content
3. 500 – The server encountered an unexpected error while processing the request and cannot continue serving requests at this time
4. 502 – The server received a response from the downstream service indicating it is unable to fulfil this request due to capacity constraints or something else preventing its completion
5. 503 – Similar to 502, except instead of telling the downstream service what is causing difficulty, 503 indicates that there is currently no space available on either side of a connection being made between these two services
How to troubleshoot failed requests using status codes.
HTTP status codes can be used to determine the cause of a failed request. Status codes indicate the success or failure of a request and can help you find out the reason for a failed request.
There are many methods you can use to troubleshoot failed requests. This guide provides an overview of four popular methods: tracing, logging, monitoring, and testing. Each method has its own advantages and disadvantages, so it’s important that you choose the right one for your situation.
Tracing is useful when you want to track down where a particular error occurred in your application code. It’s also good for understanding how different parts of your code interact with each other.
Logging helps identify problems as they happen instead of after they have caused damage.
Monitoring is helpful when trying to scale up or down your application by detecting potential issues before they become serious…
Testing allows you to safely explore potentially problematic areas without risking any data loss or user experience disruptions
Conclusion
HTTP status codes are an important part of understanding how the internet works. By understanding what they are and what they mean, you can better troubleshoot failed requests and know which status code to use when sending a request.
