Through the Ip_hash to do the session to maintain a certain defect, this is through the client IP to achieve. Many client access servers under the same network will be thrown to the same machine, or the CDN will result in unbalanced load. So to implement through the client cookie implementation, including the F5, the deep convincing device where the session remains is also by inserting a cookie value to implement session retention. The next client Acc

After configuring nginx + Tomcat, add the project to webapps. CSS and JS cannot access the homepage, leading to an error in homepage layout. After carefully analyzing the cause, we found that the CSS and JS addresses were obtained by basepath. Basepath is defined as follows: String basepath = request. getscheme () + request. getservername () + request. getserverport () + path; Where 1. Request. getscheme () returns the Protocol Name HTTP, which is combined with the following ": //" to form

Considering the shortcomings of LVS and Nginx (because LVS uses synchronous request forwarding policy and Nginx is the asynchronous forwarding policy, combined with the disadvantage of both: as the Load Balancer server nginx and LVS processing the same request, all requests and response traffic will go through the Nginx serve
