Response HeadersResponse Headers contain information sent from the server to the client in HTTP (Hypertext Transfer Protocol). They are included in the server's response to a request from the client.
Response headers provide information about the objects used in a client's request to a server in HTTP. In HTTP, the client is a World Wide Web browser. The HTTP connection consists of 1) the client contacting the server; 2) the client making a request to the server; 3) the server responding; and 4) the connection being closed.
During the request, the client sends the server specific information about the type of data to be accessed. This process is initiated when the user clicks on a hypertext link. The link contains the information the server needs to process a request. The response sent back includes response headers that contain information about the objects in the request, not the data contained in the objects. The technical term for this is Object MetaInformation. The response headers contain information about the state of the transmission, the type of data included, and the data itself. In the event that the writer of the link has specified other information acceptable for the HTTP protocol, the headers will contain this information as well.
