HTTP Status Code Lookup

HTTP status codes are standard response codes issued by web servers in response to client requests. They are grouped into five categories based on the first digit of the code:

• 1xx Informational — Request received, continuing process
• 2xx Success — Request successfully received, understood, and accepted
• 3xx Redirection — Further action needed to complete the request
• 4xx Client Error — Request contains bad syntax or cannot be fulfilled
• 5xx Server Error — Server failed to fulfill a valid request
