INTRODUCTION Map servers are applications oriented to show geographic information in a web site. These pieces of software cooperate with other applications as web servers, geographic enabled databases, etc. On the other hand, the evolution of the massive storage of images and compression algorithms allow acceding to huge amounts of geographic raster information faster and more efficient than fe...

The growth of the World Wide Web (WWW) has seen it evolve into a rich information resource. It is constantly traversed with the aid of crawlers so as to harvest web content. When collecting data, crawlers have the potential of causing service denial to web servers. This paper proposes the application of sampling as a selection strategy in the design of structural analysis web crawlers. This has...

Handle on demand network popularity of the Content Delivery Network and solve the flash crowd problem, caching web content at the internet‘s edge server has been emerged. To provide faster service of the web users, content come from nearby edge servers. Therefore nearest edge server finding of a particular web user is an open research problem and it ensures a faster response time and download t...

This paper presents the design of a new Web server architecture called the asymmetric multi process event driven AMPED architecture and evaluates the performance of an implementation of this architecture the Flash Web server The Flash Web server combines the high performance of single process event driven servers on cached workloads with the performance of multi process and multi threaded serve...

For low-latency access and scalability, Web site replication with a distributed file system has advantages over proxy caching. In particular, file systems encapsulate data consistency and recovery from failure behind a simple interface so that Web servers and Internet applications can operate as if they were on a single system. However, distributing content changes to many Web servers using a f...

World Wide Web is a huge repository of web pages and links. The Web mining field encompasses a wide array of issues, primarily aimed at deriving actionable knowledge from the Web, and includes researchers from information retrieval, database technologies, and artificial intelligence. The growth of web is tremendous as approximately one million pages are added daily. Users’ accesses are recorded...

As Internet expands, the number of application servers, especially Web servers, has been increasing exponentially. To improve the performance of Web servers, researchers have paid attention to and studied the Web server’s macro-performance, namely, the response time and throughput, which can be perceived by end users directly. In this paper, we have produced a micro benchmark, ServBench, by stu...

The loading of web servers can be very heavy and a delay in accessing certain Web sites can be substantial. Hence, the reduction of web delay is one of the important topics of research for improving the quality of service of Web pages. Thus, in this paper, we propose the web delay analysis and the web delay reduction by using load balancing coupled with the dispatcher-based approach. First, we ...

Recently there has been an increasing deployment of content distribution networks (CDNs) that offer hosting services to Web content providers. CDNs deploy a set of servers distributed throughout the Internet and replicate provider content across these servers for better performance and availability than centralized provider servers. Existing work on CDNs has primarily focused on techniques for ...

Current approaches to access control on Web servers do not scale to enterprisewide systems, since they are mostly based on individual users. Therefore, we were motivated by the need to manage and enforce the strong access control technology of RBAC in large-scale Web environments. Cookies can be used to support RBAC on the Web, holding users’ role information. However, it is insecure to store a...
