ResponseA response is the third step of the four-part HTTP connection (Hypertext Transfer Protocol). HTTP is the protocol used for accessing files on the World Wide Web.
HTTP is a very fast method of accessing information on the Internet. It achieves this by being able to process only one request per connection. The response describes the message sent to the client after a request for information has been made.
The browser used to view and access information is the client in the HTTP client/server relationship. When a user clicks on a hypertext link, the client sends the server the information contained in the chosen URL (Uniform Resource Locator, the address and protocol information of the hypertext link). This is called the request. The server responds by sending response headers that provide information about the state of the transmission (i.e., whether it was successful or not), the type of data sent, and the actual data.
