HTTP Protocol
The Web Services API provides an extensive set of operations that client applications can invoke to obtain information about the manageable resources of the system, to change those resource characteristics, and to operate on them. Because the API is designed using a web services orientation, these operations are accessed by Hypertext Transport Protocol (HTTP) messages across TCP/IP network connections.
The Web Services API has been designed in accordance with the HTTP version 1.1 protocol, as defined in the W3C internet standards document RFC 2616, Hypertext Transfer Protocol – HTTP version 1.1, June 1999. This RFC can be found in HTML format at Hypertext Transfer Protocol website .
The API requires that all clients interact using the HTTP version 1.1 protocol. The API does not support clients that use HTTP version 1.0 protocol.
HTTP Header Field Usage
HTTP request and response messages include elements known as headers fields (often referred to as headers) that provide request metadata. Certain headers are required or provided in all HTTP messages, while others are present in selected messages depending on the content.
