Lift is a free web application framework that is designed for the Scala programming language. It was originally created by (David Pollak ) who was dissatisfied with certain aspects of the Ruby on Rails framework.〔(【引用サイトリンク】title=David Pollak on lift and Scala )〕 Lift was launched as an open source project on February 26, 2007 under the Apache 2.0 license. A commercially popular web platform often cited as being developed using Lift is Foursquare.〔(【引用サイトリンク】title=Foursquare move to Scala/Lift )〕 ==Design goals and overview== Lift is an expressive framework for writing web applications. It draws upon concepts from peer frameworks such as Grails, Ruby on Rails, Seaside, Wicket and Django. It favors convention over configuration in the style of Ruby on Rails, although it does not prescribe the model–view–controller (MVC) architectural pattern. Rather, Lift is chiefly modeled upon the so-called "View First" (designer friendly) approach to web page development inspired by the Wicket framework. Lift is also designed to be a high-performance, scalable web framework by leveraging Scala actors to support more concurrent requests than is possible with a thread-per-request server. As Scala program code executes within the Java virtual machine (JVM), any existing Java library and web container can be used in running Lift applications. Lift web applications are thus packaged as WAR files and deployed on any servlet 2.4 engine (for example, Tomcat 5.5.xx, Jetty 6.0, etc.). Lift programmers may use the standard Scala/Java development toolchain including IDEs such as Eclipse, NetBeans and IDEA. Dynamic web content is authored via templates using standard HTML5 or XHTML editors. Lift applications also benefit from native support for advanced web development techniques such as Comet and Ajax. The main characteristics of Lift applications are: *Resistant to common vulnerabilities including many of the OWASP. *Fast to build, concise and easy to maintain. *High performance and scale in the real world to handle big traffic levels. *Interactive like a desktop application. 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「Lift (web framework)」の詳細全文を読む スポンサード リンク
