What is a 304?

"304" can refer to several things, depending on the context. To give you helpful information, I need more context. Is it:

  • A stainless steel grade? If so, 304 stainless steel (also known as 18/8 stainless steel) is a very common austenitic stainless steel known for its corrosion resistance, ductility, and weldability. It's widely used in kitchen appliances, cookware, and many other applications.

  • A HTTP status code? In this case, a 304 "Not Modified" response from a web server indicates that the requested resource hasn't been modified since the client's last request. The browser can then use a cached version of the resource, saving bandwidth and time.

  • A model number or code for something else entirely? (e.g., a car part, a piece of equipment, etc.) This would require more information to understand what "304" refers to.

Please clarify what you mean by "304" so I can provide you with more specific information.
