HTTP Requests

HTTP Requests

An HTTP request consists of a request method, a request URL, header fields, and a body. HTTP 1.1 defines the following request methods:

GET: Retrieves the resource identified by the request URL

HEAD: Returns the headers identified by the request URL

POST: Sends data of unlimited length to the Web server

PUT: Stores a resource under the request URL

DELETE: Removes the resource identified by the request URL

OPTIONS: Returns the HTTP methods the server supports

TRACE: Returns the header fields sent with the TRACE request

HTTP 1.0 includes only the GET, HEAD, and POST methods. Although J2EE servers are required to support only HTTP 1.0, in practice many servers, including the Sun Java System Application Server Platform Edition 8, support HTTP 1.1.
