Description: HttpResponseNotModified is a response that indicates that the resource has not been modified. This type of response is part of the HTTP protocol and is used to optimize communication between the client and the server. When a client makes a request for a resource, it can include headers that inform the server about the version of the resource it has cached. If the resource on the server has not changed since the last time the client requested it, the server can respond with a 304 (Not Modified) status code, meaning the client can continue using the cached version. This saves bandwidth and improves efficiency by avoiding unnecessary data transfer. HttpResponseNotModified is a class that facilitates the implementation of this functionality in various web frameworks, allowing developers to effectively manage their web application’s responses. Its use is especially relevant in applications that handle large volumes of data or require high efficiency in loading static resources, such as images or CSS and JavaScript files.
