How to use Nginx reverse proxy to solve cross-domain problems

How to use Nginx reverse proxy to solve cross-domain problems

The problem is in the article about cross-domain resource sharing shared before. It is mentioned that when cross-domain, if you want to send cookies, access-control-allow-origin cannot be set to *. It must be specified clearly and consistent with the requested web page. domain name. I encountered such problems when collaborating with others during the development of this project. Generally speaking, the solution is to use cors cross-domain resource sharing with the backend to set access-control-allow-origin to the domain name visited. This requires the cooperation of the backend, and some browsers do not support it. Based on the cooperation with the partner's backend, the nginx direction proxy is used to satisfy the browser's same-origin policy to implement the cross-domain implementation method reverse proxy concept.

How to limit the number of connections in nginx speed limit

How to limit the number of connections in nginx speed limit

Scenario: Company A has 100 people, and Company A only has one public IP. Assume that Company A may have 100 people downloading your website files at the same time. However, your connection limit configuration is: limit_conn_zone$binary_remote_addrzone=perip:1m;server{---limit_connperip1;limit_rate1024k;---} allows a single connection number, and the maximum bandwidth of a single connection is 1m. In this way, there will be 99 people with a request status of 503. Others must wait manually if they want to download (nginx will not notify users that user a has finished downloading, and it is your turn to download user b). The use caused by this

What are the ways Nginx implements session persistence?

What are the ways Nginx implements session persistence?

1. The session based on ip_hash is maintained. When doing Nginx load balancing, you can set ip_hash in upstream. Each request is allocated according to the hash result of the access IP and mapped to a fixed server. When the back-end server goes down, The session will be lost. When a request is made again, another normal server will be accessed again and the session will be maintained. The disadvantage is that since the same IP client always accesses a back-end server, this may lead to load imbalance. The following is the session persistence format of ip_hash. It is assumed here that the backend servers are running normally and are configured in the Nginx proxy server (load balancing server): =================
