Ocsigen is a Web application framework based on concepts derived from recent research in the field of programming languages, namely that of continuation-based web programming. It is developed in OCaml, which is also the target language for users of this framework. Ocsigen is composed of the following components: * A complete and extensible Web server, supporting features such as CGI, a reverse proxy, data compression, and access control. Extensions for this server may be written in Ocaml. * A module named Eliom for the creation of dynamic web sites using high-level abstractions. Its goal is to allow the implementation of complex behaviour using only a handful of lines, while ensuring correctness thanks to strong static typing. In particular, programmers may choose a page generation mode which enforces the output to comply with the recommendations of the W3C. This feature relies heavily on the strong static typing features of the OCaml language. Eliom allows for the entire application (both server side and client side) to be written in OCaml; compiling part of the code to JavaScript so as to be executed inside a Web Browser. Client-server bidirectional communication is abstracted away by Eliom. Data exchange between client and server is facilitated by the fact that both are implemented using the same programming language and therefore the same data types. Ocsigen uses the (Lwt ) cooperative threading library in order to handle concurrency. The word ''Ocsigen'' is a homophone of the French ''Oxygène'' (the chemical element Oxygen). Similarly, Eliom is a homophone of ''Hélium'' (the chemical element Helium). ==See also== *OCaml, the programming language used by Ocsigen *Seaside, a Web application framework for Smalltalk which is also continuation-aware 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ocsigen」の詳細全文を読む スポンサード リンク
