Load balancing system can improve the performance of a popular Web server. Most of the load balancing systems use homogeneous Web servers as their backend servers. In this situation, the dispatching algorithm can obtain load sharing among the Web servers quite easily. However, when the Web server system contains servers with different capacities, we must use factors such as the remaining capaci...

This paper studies Random Request Distribution and Load Balancing Cache protocol (RLC) and Randomly Selected and Limited Look at neighbor (RSLL) cache algorithm based on Byte Access Frequency Factor (BAFF) for internet services with multimedia and dynamic web content. The RSLL cache algorithm considers reducing response time and achieving good load balance among web servers using limitation of ...

With ever increasing Web traac, a distributed multi-server Web site can provide scalability and ex-ibility to cope with growing client demands. Load balancing algorithms to spread the requests across multiple Web servers are crucial to achieve the scalability. Various domain name server (DNS) based schedulers have been proposed in the literature, mainly for multiple homogeneous servers. The pre...

Background: Multiple sclerosis (MS) is the most common autoimmune disease of the central nervous system (CNS). The main cause of the MS is yet to be revealed, but the most probable theory is based on the molecular mimicry that concludes some infections in the activation of T cells against brain auto-antigens that initiate the disease cascade.Objectives: The Purpose of this research is the...

The Web has experienced phenomenal growth over the past few years, placing heavy load on Web servers. Today's Web servers also process an increasing number of requests for dynamic pages, making server load even more critical. The performance of Web servers delivering static pages is well-studied and well-understood. However, there has been little analytic or no empirical study of the performanc...

All successful cyber attacks begin with successful information gathering. Now more and more web servers no longer show their product tokens in the “Server” header field of the responses indiscreetly, and they want to protect the system information from reconnaissance by hiding their banners. Web servers have some unique characteristics because of different implementations and those characterist...
