Description: HttpResponseNotAllowed is a response that indicates that the method is not allowed for the requested URL. This type of response is used to handle situations where a client attempts to access a resource using an HTTP method that is not supported by the corresponding handler. For example, if a handler is configured to accept only GET requests and a client tries to make a POST request, the server will generate an HttpResponseNotAllowed response. This response is part of error handling in web applications, ensuring that users and developers receive clear information about access restrictions to resources. The HttpResponseNotAllowed class inherits from HttpResponse and is used to return an HTTP status code 405, which means ‘Method Not Allowed’. Additionally, this response can include an ‘Allow’ header that lists the allowed HTTP methods for the requested URL, helping developers understand how to correctly interact with the API or web resource. In summary, HttpResponseNotAllowed is an essential tool in developing web applications, as it contributes to robustness and clarity in communication between the server and the client.
