HTTP and REST Standards, Protocols and Headers for More Secure and More Robust Applications

Standards.REST is a website that helps you create better, more robust HTTP- and REST-based applications by providing an overview of existing, proven standards that allow you to build on existing solutions rather than re-invent the wheel yourself. The list of standards mentioned includes OAuth 2.0, the HTTP Caching standard and Application-Level Profile Semantics (ALPS), which - among others - is used extensively in Spring Data REST and Spring HATEOAS. On a closely related note, Stefan Judis published an article on HTTP headers ...
