, it is possible to make a conditional request by providing a If-modified-since header information that indicates that the client only wants the document to be modified after the specified date to be overloaded. 304 (sc_not_modified) means that the buffered version has been updated and the client should refresh the document. Additionally, the server returns the requested document and status Code 200. The servlet generally does not set this status code directly. They implement the Getlastmodified
Web application that is not a server problem, but is running on the server. For example, my own personal website is written in ASP, which is responsible for dynamically generating HTML pages. During debugging, the bug code always causes my web server to return an HTTP status code of 500, which is a general indication of an internal server error. This code only has a problem, and HTTP cannot resolve the problem.1xx– Information Tips

What is an HTTP status codeThe HTTP status code is used by the Web server to tell the client what has happened.The status code, located in the first line of HTTP Response, returns a "three-digit status code" and a "status message." The "three-digit status code" is easy for the program to process, and "status messages" are easier to understand.
