When a user agent makes a request to a server, it can request that the server respond with a 304 Not Modified status code if the user agent has a cached copy of the requested resource and the copy is up to date. This can save time and bandwidth for both the user agent and the server.

What is: HTTP 304 Not modified
What is HTTP 304?
HTTP 304 is an HTTP status code that is returned when a file or resource has not been modified. This can happen when a client makes a request to a server for a file or resource, but the server finds that the file or resource has not been modified since the last time it was requested.
When this happens, the server will return an HTTP 304 status code to the client, and the client will know that it does not need to retrieve the file or resource from the server again. This can save time and bandwidth for both the client and the server, as the server does not need to send the file or resource to the client again, and the client does not need to download the file or resource again.
HTTP 304 status codes are often used in conjunction with caching mechanisms, as they can help to reduce the amount of data that needs to be transferred between the client and the server.
How can HTTP 304 be used?
HTTP 304 can be used to improve the performance of a web application by reducing the amount of data that needs to be transferred between the client and the server. When a client requests a resource from a server, the server will check to see if the resource has been modified since the last time it was requested. If the resource has not been modified, the server can respond with an HTTP 304 Not Modified status code instead of sending the entire resource. This reduces the amount of data that needs to be transferred, which can improve the performance of the web application.
What are the benefits of using HTTP 304?
HTTP 304 is a response header that is sent back to the client to indicate that the requested resource has not been modified. This can be useful in a number of situations, such as when a client is requesting a cached version of a resource, or when a client is able to make use of a pre-fetched resource.
There are a few benefits to using HTTP 304. First, it can help reduce bandwidth usage by allowing clients to make use of cached resources, rather than having to re-download them. Second, it can improve the performance of web applications by eliminating the need to re-fetch resources that have not been modified. Finally, it can help improve security by allowing clients to only access resources that have not been modified, which can prevent them from accidentally downloading outdated or malicious versions of a resource.
How can HTTP 304 help improve your website?
HTTP 304 Not modified is an HTTP status code that is returned when a client’s request has not been modified from the server. This can be used to improve your website’s performance by caching static resources on the client’s side.
Must Read
1. HTTP 304 Not modified is an HTTP status code that indicates that a requested resource has not been modified since the last time it was accessed.
2. This status code can be used in conjunction with If-Modified-Since or If-None-Match headers to make conditional requests.
3. If the resource has not been modified since the specified time, the server will return a 304 Not Modified response. Otherwise, the server will return the resource as usual.
4. This can be useful for reducing bandwidth usage and improving page load times.
5. Note that a 304 response does not include a message body, so you will need to make a separate request for the resource if you want to access it.
