API Testing : HTTP Status Code : 304 Not Modified

HTTP status code 304, "Not Modified," is a response status code that indicates that the client's cached version of a requested resource is still valid and can be used instead of retrieving the resource from the server again.

When a client requests a resource that has previously been cached, the server may include a validation token such as an ETag or a Last-Modified header in the response to indicate the version of the resource.

When the client makes subsequent requests for the same resource, it can send a conditional request that includes the validation token in the request headers.

If the server determines that the cached version of the resource is still valid based on the validation token, it can return a 304 status code instead of returning the full resource again.

This status code is commonly used to reduce network traffic and improve performance by minimizing the number of requests between the client and server for resources that have not changed since the last request.

It's important to note that the 304 status code should only be used for GET and HEAD requests, as these requests do not modify any resources on the server.

For other types of requests, such as POST or PUT, other status codes such as 200 or 204 should be used instead.
