HTTPStatusmeldungen

HTTP Status Codes, also known as HTTP status messages or HTTP response status codes, are a set of codes issued by web servers to inform the client, typically a web browser, about the outcome of a request. These codes are part of the Hypertext Transfer Protocol (HTTP) and are essential for understanding and debugging web communication. They are represented by a three-digit integer.

The status codes are categorized into five classes, each indicated by the first digit of the code. Class 1xx codes are informational, indicating that the request has been received and the server is continuing to process it. Class 2xx codes indicate success, meaning the client's request was successfully received, understood, and accepted. Class 3xx codes are for redirection, signifying that further action needs to be taken by the client to complete the request. Class 4xx codes represent client errors, meaning the request contains bad syntax or cannot be fulfilled. Finally, class 5xx codes denote server errors, indicating that the server failed to fulfill an apparently valid request.

Commonly encountered status codes include 200 OK, indicating a successful request; 404 Not Found, meaning the requested resource could not be found on the server; and 500 Internal Server Error, signifying an unexpected condition encountered by the server. Understanding these codes is crucial for web developers and administrators for diagnosing issues and ensuring smooth operation of websites and web applications.
