In our example, the zone is named client_sessions and is 1 megabyte in size. The mandatory zone parameter specifies a shared memory zone where all information about sticky sessions is kept. In our example, existing sessions are searched in the cookie EXAMPLECOOKIE sent by the client.
#Minecraft switch invalid session how to
The mandatory lookup parameter specifies how to search for existing sessions.
In the example, new sessions are created from the cookie EXAMPLECOOKIE sent by the upstream server. The mandatory create parameter specifies a variable that indicates how a new session is created.
In the example, one of the upstream servers creates a session by setting the cookie EXAMPLECOOKIE in the response.
Sticky learn create=$upstream_cookie_examplecookie

The client’s next request contains the cookie value and NGINX Plus route the request to the upstream server that responded to the first request: Sticky cookie – NGINX Plus adds a session cookie to the first response from the upstream group and identifies the server that sent the response. (For session persistence with NGINX Open Source, use the hash or ip_hash directive as described above.) The methods are set with the sticky directive. NGINX Plus supports three session persistence methods. Session persistence means that NGINX Plus identifies user sessions and routes all requests in a given session to the same upstream server. Note that if there is only a single server in a group, the max_fails, fail_timeout, and slow_start parameters to the server directive are ignored and the server is never considered unavailable.

The time value (here, 30 seconds) sets the time during which NGINX Plus ramps up the number of connections to the server to the full value. last_byte inflight – Time to receive the full response from the server, taking into account incomplete requests.last_byte – Time to receive the full response from the server.header – Time to receive the first byte from the server.Least Time (NGINX Plus only) – For each request, NGINX Plus selects the server with the lowest average latency and the lowest number of active connections, where the lowest average latency is calculated based on which of the following parameters to the least_time directive is included: If an upstream server is added to or removed from an upstream group, only a few keys are remapped which minimizes cache misses in the case of load‑balancing cache servers or other applications that accumulate state. Requests are evenly distributed across all upstream servers based on the user‑defined hashed key value. The optional consistent parameter to the hash directive enables ketama consistent‑hash load balancing. For example, the following configuration defines a group named backend and consists of three server configurations (which may resolve in more than three actual servers): Servers in the group are configured using the server directive (not to be confused with the server block that defines a virtual server running on NGINX). The directive is placed in the http context. To start using NGINX Plus or NGINX Open Source to load balance HTTP traffic to a group of servers, first you need to define the group with the upstream directive. Proxying HTTP Traffic to a Group of Servers
NGINX and NGINX Plus can be used in different deployment scenarios as a very efficient HTTP load balancer. Watch the NGINX Plus for Load Balancing and Scaling webinar on demand for a deep dive on techniques that NGINX users employ to build large‑scale, highly available web services. Load balancing across multiple application instances is a commonly used technique for optimizing resource utilization, maximizing throughput, reducing latency, and ensuring fault‑tolerant configurations. Load balance HTTP traffic across web or application server groups, with several algorithms and advanced features like slow-start and session persistence.
