Cross-Domain Embedding for Vaadin Applications
Cross-Domain Embedding for Vaadin Applications Janne Lautamäki and Tommi Mikkonen Department of Software Systems, Tampere University of Technology, Korkeakoulunkatu 1, FI-33720 Tampere, Finland {janne.lautamaki,tommi.mikkonen}@tut.fi Abstract. Although the design goals of the browser were originally not at running applications or at displaying a number of small widgets on a single web page, today many web pages considerably benefit from being able to host small embedded applications as components. While the web is full such applications, they cannot be easily reused because of the same origin policy restrictions that were introduced to protect web content from potentially malicious use. In this paper, we describe a generic design for cross domain embedding of web applications in a fashion that enables loading of applications from different domains as well as communication between the client and server. As the proof- of-concept implementation environment, we use web development framework Vaadin, a Google Web Toolkit based system that uses Java for application development. Keywords: Vaadin, JSONP, cross-domain applications. 1 Introduction Web applications – systems that resemble desktop applications in their behavior but are run inside the browser – are becoming increasingly common. The current trend is that web pages have dynamic components side by side with the traditional web content, such as static text and images. These dynamic components can be small widgets that for instance display current weather information or stock exchange data, or even full-fledged web applications that offer a service related to the theme of the web page where they are located [1]. Creating dynamic web pages is much more complex than building plain old web pages. -

Chapter 1 Web Basics and Overview
Chapter 1 Web Basics and Overview The Web is an Internet-based distributed information system. Anyone with a computer connected to the Internet can easily retrieve information by giving a Web address or by simply clicking a mouse button. The Web is a great way to disseminate information and making it available 24/7. Information can also be collected from Web users and customers through online forms. Maintainers and administrators can control and update Web content from anywhere on the Web. All these make the Web a powerful tool for mass communication, e-business and e-commerce. Compared with TV, radio, news papers, and magazines, putting the word out on the Web is relatively simple and inexpensive. But a website is much more than such one-way communication media. It can be a virtual o±ce or store that is always open and supported by workers from anywhere. Web service companies o®er free Web space and tools to generate simple personal or even business Web pages. But, well-designed and professionally implemented websites are much more involved. Even then, expertly produced websites are still much more cost-e®ective than other means of mass communication. For business and commerce, the cost of a website is negligible when compared to building and operating a brick-and-mortar o±ce or store. Once in-place, a website is a store that never closes and that is very attractive. People take great pains in building an o±ce or store to project the right image and to serve the needs 7 8 CHAPTER 1. -
Web Pages Are Stored on Web Server and Can Be Viewed Using a Web Browser
WWEEBB PPAAGGEESS http://www.tutorialspoint.com/internet_technologies/web_pages.htm Copyright © tutorialspoint.com Web Page web page is a document available on world wide web. Web Pages are stored on web server and can be viewed using a web browser. A web page can cotain huge information including text, graphics, audio, video and hyper links. These hyper links are the link to other web pages. Collection of linked web pages on a web server is known as website. There is unique Uniform Resource Locator URL is associated with each web page. Static Web page Static web pages are also known as flat or stationary web page. They are loaded on the client’s browser as exactly they are stored on the web server. Such web pages contain only static information. User can only read the information but can’t do any modification or interact with the information. Static web pages are created using only HTML. Static web pages are only used when the information is no more required to be modified. Dynamic Web page Dynamic web page shows different information at different point of time. It is possible to change a portaion of a web page without loading the entire web page. It has been made possible using Ajax technology. Server-side dynamic web page It is created by using server-side scripting. There are server-side scripting parameters that determine how to assemble a new web page which also include setting up of more client-side processing. Client-side dynamic web page It is processed using client side scripting such as JavaScript. -

Cascading Style Sheet Web Tool
CASCADING STYLE SHEET WEB TOOL _______________ A Thesis Presented to the Faculty of San Diego State University _______________ In Partial Fulfillment of the Requirements for the Degree Master of Science in Computer Science _______________ by Kalthoum Y. Adam Summer 2011 iii Copyright © 2011 by Kalthoum Y. Adam All Rights Reserved iv DEDICATION I dedicate this work to my parents who taught me not to give up on fulfilling my dreams. To my faithful husband for his continued support and motivation. To my sons who were my great inspiration. To all my family and friends for being there for me when I needed them most. v ABSTRACT OF THE THESIS Cascading Style Sheet Web Tool by Kalthoum Y. Adam Master of Science in Computer Science San Diego State University, 2011 Cascading Style Sheet (CSS) is a style language that separates the style of a web document from its content. It is used to customize the layout and control the appearance of web pages written by markup languages. CSS saves time while developing the web page by applying the same layout and style to all pages in the website. Furthermore, it makes the website easy to maintain by just editing one file. In this thesis, we developed a CSS web tool that is intended to web developers who will hand-code their HTML and CSS to have a complete control over the web page layout and style. The tool is a form wizard that helps developers through a user-friendly interface to create a website template with a valid CSS and XHTML code. -
Revisiting XSS Sanitization
Revisiting XSS Sanitization Ashar Javed Chair for Network and Data Security Horst G¨ortzInstitute for IT-Security, Ruhr-University Bochum [email protected] Abstract. Cross-Site Scripting (XSS) | around fourteen years old vul- nerability is still on the rise and a continuous threat to the web applica- tions. Only last year, 150505 defacements (this is a least, an XSS can do) have been reported and archived in Zone-H (a cybercrime archive)1. The online WYSIWYG (What You See Is What You Get) or rich-text editors are now a days an essential component of the web applications. They allow users of web applications to edit and enter HTML rich text (i.e., formatted text, images, links and videos etc) inside the web browser window. The web applications use WYSIWYG editors as a part of comment functionality, private messaging among users of applications, blogs, notes, forums post, spellcheck as-you-type, ticketing feature, and other online services. The XSS in WYSIWYG editors is considered more dangerous and exploitable because the user-supplied rich-text con- tents (may be dangerous) are viewable by other users of web applications. In this paper, we present a security analysis of twenty five (25) pop- ular WYSIWYG editors powering thousands of web sites. The anal- ysis includes WYSIWYG editors like Enterprise TinyMCE, EditLive, Lithium, Jive, TinyMCE, PHP HTML Editor, markItUp! universal markup jQuery editor, FreeTextBox (popular ASP.NET editor), Froala Editor, elRTE, and CKEditor. At the same time, we also analyze rich-text ed- itors available on very popular sites like Twitter, Yahoo Mail, Amazon, GitHub and Magento and many more. -

The definition of HTTP is a technical specification of a network protocol that software must implement. HTTP is an application layer network protocol built on top of TCP. HTTP clients (such as Web browsers) and servers communicate via HTTP request and response messages. The three main HTTP message types are GET, POST, and HEAD. HTTP utilizes TCP port 80 by default, though other ports such as 8080 can alternatively be used……. “ http://compnetworking.about.com/od/networkprotocols/g/bldef_http.htm HTTPS The secure hypertext transfer protocol (HTTPS) is a communications protocol designed to transfer encrypted information between computers over the World Wide Web. HTTPS is http using a Secure Socket Layer (SSL). A secure socket layer is an encryption protocol invoked on a Web server that uses HTTPS. Most implementations of the HTTPS protocol involve online purchasing or the exchange of private information. Accessing a secure server often requires some sort of registration, login, or purchase. The successful use of the HTTPS protocol requires a secure server to handle the request. http://msdn.microsoft.com/en-us/library/aa767735(v=vs.85).aspx HTML HyperText Markup Language is used for describing web documents (web pages) so that they can be correctly displayed. A markup language is a set of markup tags HTML documents are described by HTML tags Each HTML tag describes different document content http://www.w3schools.com/html/html_intro.asp Static Web Page A web page that uses only HTML does not change its appearance or its data and is therefore always a static webpage URI and URL In computing, a uniform resource identifier (URI) is a string of characters used to identify a name of a resource. -
