Distributed Web caching allows multiple clients to quickly access a pool of popular Web pages. Conventional distributed Web caching schemes, e.g., the Internet cache protocol and hash routing, require the sending of many query messages among cache servers and/or impose a large load on the cache servers when they are widely dispersed. To overcome these problems, we propose a hash-based query cac...

As mobile devices and broadband networks are widely available, it is desirable to provide mobility for web services. A web service is mobile in the sense that, without interrupting the services, users are allowed to switch the browsing devices or the service providing servers could be changed as the users move. The mobility of users’ browsing devices and the change of service providing servers ...

Users clamor for online services hosted on remote web servers. As a result, there is a growing concern about the security and privacy of the data uploaded by users to such remote services, which are under the control of potentially untrusted parties. A fair amount of work has focused on preventing, detecting, and correcting security breaches of web services, with limited efforts spent on the pr...

Too often, “security of Web transactions” reduces to “encryption of the channel”—and neglects to address what happens at the server on the other end. This oversight forces clients to trust the good intentions and competence of the server operator—but gives clients no basis for that trust. Furthermore, despite academic and industrial research in secure coprocessing, many in the computer science ...

We believe that storing web annotations on annotation servers limits the widespread adoption of web annotation technology. Instead of relying on annotation servers, we propose to encode annotations as an extended URL. Because they follow the standard URL encoding, these extended URLs can be readily used and embedded in Web documents. We then envision specific search engines that would be able t...

VoiceXML [1], or Voice extensible Markup Language, is a special markup language designed to facilitate the creation of speech application, especially interactive voice response (IVR) application. At the difference of conventional IVR programming frameworks, that involve proprietary scripts and programming languages over proprietary / closed platforms, VoiceXML provides a declarative, programmin...

Multimedia data is characterized by large objects that require high-bandwidth. This paper presents a technique that enables efficient and dependable data storage and delivery of large multimedia objects in the World Wide Web environment. The proposed approach strips data into blocks that are distributed over multiple Web servers. Data distribution is transparent to users. The parallelism of mul...

E-commerce server reliability is critical, as downtimes cost an average of $10,000 per minute [40]. Commercial web server development today is done with fairly generic programming languages, like Java, Perl, and C#. The generality of these languages, while permitting a wide range of target applications, makes it difficult to guarantee reliability: dynamic type errors, race conditions, and resou...

We investigate data organization in the World Wide Web In order to extend traditional database techniques to the Web we concentrate on structured Web servers those servers now very common in which data are organized according to precise structures and pages present strong regularities The paper introduces several tools for the management of structured servers We present a page oriented data mod...
