What Does Representational State Transfer Mean?

Roy Fielding, one of the main authors of the HTTP specification, evolved the REST idea in 2000 as part of his doctoral dissertation.

REST can be used to seize Internet site Records through interpreting Extensible Markup Language (XML) Web Page Files with the preferred facts. In addition, on-line publishers use REST whilst supplying syndicated content material to users through activating Web page content and XML statements. Users might also Access the Web page via the Website's URL, read the XML file with a Web Browser, and interpret and use facts as needed.

Basic REST constraints encompass:

• Client and Server: The patron and server are separated from REST operations via a uniForm Interface, which improves consumer Code Portability.
• Stateless: Each purchaser request must contain all required records for request processing with out storing customer Context at the server.
• Cacheable: Responses (inclusive of Web pages) may be cached on a consumer Computer to hurry up Web Browsing. Responses are defined as cacheable or now not cacheable to prEvent clients from reusing stale or irrelevant statistics whilst responding to in addition requests.
• Layered System: Enables customers to connect to the cease server via an interMediate layer for advanced Scalability.
