Multiple Proxy Servers

A proxy server is a computer that is not able to perform an operation on its own, which is the proxy server that performs the operation through a single server. The proxy server is the network Service technology which comes into being with the Internet, it can realize the security filtering of the network, the flow control (reduce Internet usage fee), the user manages and so on function, so the proxy server is very useful to the user of the home network, small enterprise network. It can not only solve many units connected to the Internet caused by insufficient IP address, but also ...

For small and medium-sized enterprises or the company's internal network as well as the Internet, through the Wingate agent to achieve access to the Internet, is an economic and practical program. Wingate's current popular version is WinGate5.0.1, which is divided into simple and professional editions (its free trial version can be downloaded from Internet sites: http://www.wingate.com.cn, etc.). This article will use the most extensive WinGate5.0.1 Professional edition, talk about its configuration and the use of some of the skills in the process. WinGate ...

Do you want to expose a Domino HTTP server address to a public network due to well-known security considerations? Can multiple Domino servers use only one address? This demand is growing in the context of deploying Domino. These can be implemented as Domino's reverse proxy (reverse proxy) by installing the Apache HTTP server. Why choose Apache HTTP Server First, it is an open source project, document source code can ...

A network bridge is a device that is installed on a network and does not require any subsequent configuration. The network switch is basically a multiple-port network bridge. This means that the bridge is a two-port switch. Linux can support a network bridge with multiple interfaces and become a real exchanger. Bridges are often used to improve networks that http://www.aliyun.com/zixun/aggregation/7317.html "> work poorly but cannot be rebuilt." Because the bridge is a 2-layer device (IP below the layer), ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; The concept of clustering is easily confused with concepts (SMP, NUMA, MPP, distributed processing), whose primary difference is in the level at which resources are shared and replicated. 　　They are arranged by SMP, NUMA, MPP, clustering, and distributed processing from the most compact to the most loosely aligned. Because of the current network of the core parts with ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; With the increase of traffic volume and the rapid growth of traffic volume and data flow, the processing capacity and computing strength of the existing network have been increased correspondingly, so that single server equipment cannot afford it at all. In this case, if you throw away the existing device to do a lot of hardware upgrades, this will cause the waste of existing resources, and if again ...

The intermediary transaction SEO diagnose Taobao guest Cloud host technology lobby safe Internet, the first step is to choose a safe and reliable and fast proxy server as the first level agent. Now many Web sites posted on the proxy server, there are a lot of bad, and easy to use the possible speed is not ideal, because we generally use the method of double agent encryption online, if the first agent is not good, it will cause login failure. So I think choosing a safe and fast first level agent is the basis of safe Internet access. This article on how to choose a first-class agent, my experience to write, for large ...

The rapid growth of the Internet makes multimedia network servers, especially the http://www.aliyun.com/zixun/aggregation/17117.html ">web servers, face a rapid increase in the number of visitors, Network servers require the ability to provide a large number of concurrent access services. For example, Yahoo receives millions of requests per day for access, so CPU, I/O processing capacity will quickly become a bottleneck for servers that provide large-load Web services. &n ...

In most IT organizations, virtual servers are backed up in the same way as physical servers in the early stages, but as the number of virtual servers increases, traditional backup methods start to get out of place. 　　In fact, many virtual machines (VMS) reside on a single physical machine and pose many challenges, which do not exist when a separate backup to a physical server exists. Multiple virtual opportunities compete for resources such as processes, storage, and networks, which are the biggest challenges to data protection for virtual servers. Parallel backup jobs for multiple virtual machines can seriously affect the nature of applications deployed on these virtual machines ...
