This paper presents the design of a new Web server architecture called the asymmetric multiprocess 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 singleprocess event-driven servers on cached workloads with the performance of multi-process and multithreaded ser...

There are a number of factors that contribute to the performance between clients and servers in the World Wide Web. In this work we have concentrated on the contribution of DNS lookup to the overall Web object retrieval time. We found that the DNS mechanism performed better for popular Web servers than for random Web servers. Performance was better both in terms of local cache hit rates, which ...

An increasing number of countries and companies routinely block or monitor access to parts of the Internet. To counteract these measures, we propose Infranet, a system that enables clients to surreptitiously retrieve sensitive content via cooperating Web servers distributed across the global Internet. These Infranet servers provide clients access to censored sites while continuing to host norma...

web is a rich domain of opportunities, where different kind of data and knowledge is available. To get advantage of these data a huge amount of internet users access the web. The content distribution over internet is a complex task, in this process a number of intermediate proxy servers, ISP servers are participating. In order to get advantage of the distributable contents on client end web pre...

The continuing growth of the World-Wide Web is placing increasing demands on popular Web servers. Many of the sites are now using distributed Web servers (i.e., groups of machines) to service the increasing number of client requests, as a single server cannot handle the workload. Incoming client requests must be distributed in some fashion among the machines in the distributed Web server to imp...

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...

With the rapid growth of the World Wide Web, clients attempting to access some popular web sites are experiencing slow response times due to server load and network congestion. Replacing the single server machine with a set of replicated servers is a cost-effective solution to partition server load which also allows incremental scalability and fault transparency. Distributing these replicated s...

A Web server’s constraint on the number of pages it can serve simultaneously is largely because of two factors: the bandwidth available and the Web server itself. When a website is popular and if there is only one web server responding to all the incoming HTTP requests for a website it may be possible that the capacity of the web server may not be able to handle high volumes of incoming traffic...

This paper provides two contributions to the study of highperformance object-oriented (OO) Web servers. First, it outlines the design principles and optimizations necessary to develop efficient and scalable Web servers and illustrates how we have applied these principles and optimizations to create JAWS. JAWS is a high-performance Web server that is explicitly designed to alleviate overheads in...
