  HTTP actions and List of  all HTTP actions that know,
.
HTTP:
The hypertext transfer protocol is an application protocol for the distribution, collective helper medium information systems. Http is the base of the World Wide Web. Hypertext is structural text that uses logical links between nodes containing text. Http is the protocol to exchange or transfer Hypertext.
Http action
An Http session is a sequence of network request response transactions. An HTTP client starts a request by establishing a transmission control. During this transactions Http perform different action. These actions perform different parts of the HTTP. These parts are divided into the six parts.


1)       Message syntax and Routing
The http is a application level protocol for distributed, community oriented, hyper taxt data pfamework. This archive give  an http engineering and its related pharasing, characterizes the “http” and “https” uniform asset identifier plans, characterizes the message language structure and parsing necessities and portrays related security attentiveness toward executions.
2)      Semantics and contents
Some http message transfer a complete and a part of message “payload”. The purpose of payload should be defined by the semantic method. For example when we payload a put message request represent the desired state of the target resource.If the request is successful accessed.Otherwise a payload of a post request represent information to be proceded by the target resource.
                There are two types of content that could be made visible with the protocol. “proactive” where the server selects the representation based upon the user agents stated performatnce. Other type is content negotiation.
3)      Conditional Requests
The HTTp protocol has a caching machine in which the proxy web servers have cache page. There is a method which the server are asked to return the document either the “cached” or “live” document. This request asking the server for a document understand a specific pattern is called a conditional request.
4)      Range Requests
A HTTp may request partial entity has using a range header.Range request may decrease bandwidth usage and response times. But they present serious protocol and performace challenges for caching proxies Http range functionality in RFC.
5)      Caching
Caching would be useless if it did not perform his improvement. The purpose of caching send request in many cases and send full responses in many other cases.
6)      Authentication
HTTP support the use of several authentication mechanism to control access to pages and other resources.This is based on the use of 401 status code and the www. Authenticate response header.
