How to REST?

An article, posted 12 months ago filed in , , , , , , , , & .

Today I tried to explain REST (as in REpresentational State Transfer, not near sleep) to a manager and why some of the services deployed at the organization he was working for wasn't REST. While there isn't a formalized spec, there is a dissertation by the Roy Fielding, who came up with the REST-principles as a set of principles that guided him while shaping the HTTP 1.1 standard which only recently got a successor with version 2.0… REST is a set of principles/guidelines that are very stable & predictable. It is also very simple, and theirin lies both its strength, and the sometimes too loose application of its principles.

Apparently many developers didn't get 'the web' (HTTP) right, hence REST was developed as a basic set of principles to explain how HTTP is supposed to work. This is a list of my favourite parts, also based on some secondary resources.

Some key concepts.

Still waiting for pipe-lining to become mainstream

Sometimes I get a bit upset about a state a project I get to work on is in. Recently I came across a project which frontend served over 30 files that could be reduced easily to about 10. I got upset because to me it is like one of the basic things you have to be aware of as a web developer. I told the others working on the project that is a problem that should be fixed, to optimize speed. But later that day, in bed, I started wondering because the pages were served using HTTPS: was I actually correctin stating it as a problem? Well, currently still yes.

I started wondering because I remembered something about 'pipe-lining'. A year ago I turned on the experimental SPDY protocol a year ago, which supports asynchronous pipe-lining. Pipe-lining allows browsers to request all files in one request, which diminishes the reason why a developer should try to reduce the numbers of file…

BookReview: RESTful Web Services

An article, posted more than 11 years ago filed in , , , , , , , , , , , , , , & .

Web Services hebben we het over het gedeelte van het internet dat begrepen kan worden, in tegenstelling tot het gewone web van web sites, door computer systemen. Er zijn verschillende manieren hoe je computer A over het internet met computer B kunt laten praten, en de RESTful wijze is er daar 1 van. In het boek RESTful Web Services, geschreven door Leonard Richardson en Sam Ruby (ISBN nr.: (978) 0596529260), wordt deze wijze uitgebreid behandeld.

Ten opzichte van andere manieren van communiceren over het internet is dat het uit gaat van de eenvoud van het HTTP protocol, dit in tegenstelling tot b.v. SOAP en RPC. Hoewel ook deze technologiën uiteindelijk wel over het HTTP gaan hebben deze technologiën een geheel andere benadering in de wijze waarin informatie op gevraagd en gemanipuleerd kan worden. Deze benadering is resource oriented, i.p.v. activity oriented. In plaats van de actie die veelal centraal staat …
