The WebSocket Protocol

Abstract: The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. The security model used for this is the origin-based security model commonly used by web browsers. The protocol consists of an opening handshake followed by basic message framing, layered over TCP. The goal of this technology is to provide a mechanism for browser-based applications that need two-way communication with servers that does not rely on opening multiple HTTP connections (e.g., using XMLHttpRequest or s and long polling).

Building rich web applications with Ajax

Abstract: Looks at how developers are going back to the future by building Web applications using Ajax (Asynchronous JavaScript and XML), a set of technologies mostly developed in the 1990s. A key advantage of Ajax applications is that they look and act more like desktop applications. Proponents argue that Ajax applications perform better than traditional Web programs. As an example, Ajax applications can add or retrieve new data for a page it is working with and the page will update immediately without reloading.

Web server providing role-based multi-level security

Abstract: A system for enabling access to non-HTML files from a web browser. The system includes a database for storing non-HTML files. A system user requests a non-HTML file from a database using a web browser. The web browser transmits the request to a server via a HTTP server and module. The server locates and retrieves the document requested. The interface module converts the document to a format supported by the web browser. The HTTP server communicates the converted file to the web browser over a network. The web browser then presents the converted file to the system user. The interface module comprises a security module which controls access to documents within the system. The security module assigns a priority level to a user. The priority level is used to grant or deny access to the documents or fields within the documents. The security module also provides user authentication and authorization.

Web server with integrated scheduling and calendaring

Abstract: A system for enabling access to non-HTML objects from a web browser. The system includes a database for storing non-HTML objects. A system user requests a non-HTML object from a database using a web browser. The web browser transmits the request to a server via a HTTP server and module. The server locates and retrieves the document requested. The module translates the document to a format supported by the web browser. The HTTP server communicates the translated object to the web browser over a network. The web browser then presents the translated object to the system user. The server also includes a schedule and calendar application which provides electronic scheduling and calendaring capabilities directly from the browser without having to open another application or display window.

Ajax Design Patterns

Abstract: Ajax, or Asynchronous JavaScript and XML, exploded onto the scene in the spring of 2005 and remains the hottest story among web developers. With its rich combination of technologies, Ajax provides a strong foundation for creating interactive web applications with XML or JSON-based web services by using JavaScript in the browser to process the web server response.Ajax Design Patterns shows you best practices that can dramatically improve your web development projects. It investigates how others have successfully dealt with conflicting design principles in the past and then relays that information directly to you.The patterns outlined in the book fall into four categories:Foundational technology: Examines the raw technologies required for Ajax developmentProgramming: Exposes techniques that developers have discovered to ensure their Ajax applications are maintainableFunctionality and usability: Describes the types of user interfaces you'll come across in Ajax applications, as well as the new types of functionality that Ajax makes possibleDevelopment: Explains the process being used to monitor, debug, and test Ajax applicationsAjax Design Patterns will also get you up to speed with core Ajax technologies, such as XMLHttpRequest, the DOM, and JSON. Technical discussions are followed by code examples so you can see for yourself just what is-and isn't-possible with Ajax. This handy reference will help you to produce high-quality Ajax architectures, streamline web application performance, and improve the user experience.Michael Mahemoff holds a PhD in Computer Science and Software Engineering from the University of Melbourne, where his thesis was "Design Reuse in Software Engineering and Human-Computer Interaction." He lives in London and consults on software development issues in banking, health care, and logistics."Michael Mahemoff's Ajax Design Patterns is a truly comprehensive compendium of web application design expertise, centred around but not limited to Ajax techniques. Polished nuggets of design wisdom are supported by tutorials and real-world code examples resulting in a book that serves not only as an intermediate to expert handbook but also as an extensive reference for building rich interactive web applications." --Brent Ashley, remote scripting pioneer
