The 304 Not Modified response is an HTTP status code.
It tells the client (like a web browser or crawler) that the requested resource has not been changed since the last time it was accessed.
That means the browser can use the cached version of the resource, saving time and bandwidth.
Here’s an example:
When you visit a website, your browser asks the website’s server for the page. The server sends the page back and your browser shows it to you.
This happens every time you visit a new website. But asking for pages takes time and uses tons of data.
This is where the 304 Not Modified response comes in.
Think of it like a sign at the front of your website server telling the browser, “This page hasn’t changed since your last visit.”
This means your browser doesn’t need to do all of that work to get the page again. Instead, it uses the saved version from your computer’s memory.
This makes the website load faster because it doesn’t have to download everything again.
Pretty cool, right?
The 304 Not Modified response code is important because it tells the client (web browser, crawler) the page hasn’t changed since the last visit.
This is essential for web performance and efficient website management.
These are some of the biggest benefits:
The bottom line is that 304 Not modified response code greatly benefits website owners AND users.
It will use less bandwidth from your server, which means you will spend less money on server fees.
Your users will also benefit from faster load times and better website performance.
That’s a win-win.
