1. How the Cache worksWeb cache, as a Web caching technology, can be implemented on any intermediate network element where a user accesses a Web server. According to the definition of HTTP protocol, in one page access, the user requests from the client to the Web server in response to the request content of the interaction process, usually involves 4 key network elements: users, agents, gateways and WEB servers.

reverse proxy server. Reverse proxy is one of the mainstream means to achieve load balancing, usually using Nginx and other servers to build, Nginx also has a number of allocation strategies to ensure the average distribution of pressure.Nginx Reverse Proxy:BIGIP (Hardware) Load balancing:2) CDNVideo is always in the buffer, pictures of various loading not come out, a few years ago is normal but the matter, at that time we did not feel that the matter, but put this situation in the present, I t

the only line. That's pretty thorough. DNS polling is the simplest and most effective way to achieve load balancing, with very low cost in all respects. The goods are very cheap and enough. The disadvantage is that because there is no detection mechanism, not balanced, fault-tolerant response time is long. Domestic portal with a lot of this technology, with squid has a very good effect. Of course, without load balancing, pulling several lines directly from multiple ISPs, providing services
