200 OK Code
The HTTP status code 200 OK is the most common server code, and is the standard response for successful HTTP requests ,this is what will be returned by default when a web page is successfully served up.
The actual successful information returned with the response is dependent on the method used in the request, for instance: In a GET an entity corresponding to the requested resource is sent in the response. In a HEAD the entity-header fields corresponding to the requested resource are sent in the response without any message-body. In a POST an entity describing or containing the result of the action. In a TRACE an entity containing the request message as received by the end server.
