A content delivery network (CDN) is composed of several edge servers which are distributed in different regions and provide web objects locally. If a web client sends one request to an edge server that has no available cache, i.e., cache miss, this edge server must download web objects from other edge servers or the origin server and then store into the cache. In this paper, we study and implement...
In 2014 over 70% of people in Great Britain accessed the Internet every day. This resource is an optimal vector for malicious attackers to penetrate home computers and as such compromised pages have been increasing in both number and complexity. This paper presents X-Secure, a novel browser plug-in designed to present and raise the awareness of inexperienced users by analysing web-pages before malicious...
Currently, most of the existing web cache replacement strategies are based on temporal locality, frequency distribution and size distribution while spatial locality gets less attention. This paper proposed a reference model to evaluate the spatial locality of web object accessing, and used the reference model as the basis of a new cache replacement strategy -- GDSR, Greedy-Dual-Size Reference. GDSR...
World Wide Web is an enormous store of links and web pages. It provides huge amount of information for the Internet clients. The development of web is great as about one million pages are added every day. Users' accesses are traced in web logs. Because of the great usage of web, the web log files are increasing at a more rapidly rate and the range is becoming enormous. Web Usage Mining relates mining...
Brief episodes of network faults and performance issues adversely affect the user Quality of Experience (QoE). Besides damaging the current opinions of users, these events may also shape user's future perception of the service. Therefore, it is important to quantify the impact of such events on QoE over time. In this paper, we present our findings on the temporal aspects of user feedback to disturbances...
Nowadays, use of web has increased. User search a web corresponds to a query. Search engine provide indexed result for the users. Clickstream analysis is a new approach for web page importance calculation. User uses some clicks on the results according to the search result. These clicks are stored on server log file. Server log file store the order sequence of user clicks after that these clicks can...
Internet topic detection and classification is an intelligent information access technology. It studies how to detect new events and classify sentiment of the content. Classical detection and analysis system of internet topics has low analysis efficiency and large process delay. The functions of cluster-based analysis system are internet data collection, real-time analysis and off-line data analysis...
We propose an efficient technique for slicing web applications. First we construct the system dependence graph for a web application and then perform backward slicing on that graph corresponding to a given slicing criterion. We use Java server pages for the web application.
Great many Websites exist present. These Websites are developing various services to accommodate many customers. This time, several kinds of links exist to website. But, size of early service Web page increased as numbers of this service increase greatly. A lot of links give load to Web server. When several users approached for Web page, a lot of links can give decline in the service speed. We made...
The TENCompetence project has made the first release of IMS LD tools which provide significant improvements in usability and integration. The project and the user group are introduced, and the principal improvements described. The results of initial evaluation are outlined, and the direction of future work is indicated.
This paper presents an advanced approach to access control on the Web. It presents an easy deployable package that exploits emerging trust negotiation approaches by integrating them in a Web scenario. In such a scenario advance decisions can be made based on expressive conditions, including credentials exchanged among entities in order to establish enough trust to be granted access to a resource,...
