HTTP error codes are the response provided by an HTTP server when a request from the browser is not successful. These codes are used to identify and explain why a request has failed and provide guidance on how to fix the issue. There are five main categories of HTTP errors: 1xx Informational, 2xx Successful, 3xx Redirection, 4xx Client Error, and 5xx Server Error. Each of these categories have a range of specific codes associated with them.
1xx Informational errors indicate that the request was received and understood by the server, but no further action is required; these messages are rare and mostly for informational purposes. As such, these codes include 100 Continue (request was received), 101 Switching Protocols (server understands), 102 Processing (server is still processing), 103 Early Hints (indication of server’s intentions).
2xx Successful codes refer to requests that have been successfully completed by the server; some examples of this category include 200 OK (standard response for successful request completion), 201 Created (resource was successfully created), 202 Accepted (request accepted but not yet processed or fulfilled).
3xx Redirection messages inform the browser that it needs to take additional action in order to complete the request; some common ones here include 301 Moved Permanently (URL has moved permanently) 302 Found/Moved Temporarily (URL has moved temporarily) 304 Not Modified (cached version of requested file is current).
4xx Client Errors refer to issues related to what was submitted in a request from the client side; some examples here include 400 Bad Request (general syntax error), 401 Unauthorized (no authentication credentials were sent with request), 403 Forbidden (client does not have access rights to resource), 404 Not Found (requested resource cannot be located).
Finally, 5xx Server Errors refer to issues with the server itself preventing it from completing a valid request; some typical ones within this group include 500 Internal Server Error (general problem with server internal operations) 501 Not Implemented (server does not know how to fulfill requested action) 502 Bad Gateway/Proxy Error (incompatible proxy or gateway server unable to complete request).
HTTP error codes can be extremely helpful when troubleshooting web related problems as they quickly identify where an issue lies while providing useful tips on how it can be fixed. They should always be checked first if there is any suspicion that something might have gone wrong in an online transaction as they provide invaluable insight into potential causes and solutions allowing users/developers alike quickly resolve problems without guesswork.
