proxy_read_timeout

Описание

The `proxy_read_timeout` directive defines the timeout period for reading data from the proxied server (i.e., the server that NGINX is forwarding requests to). If the proxied server does not send any data within this time frame, then NGINX will terminate the connection and return an error to the client. This timeout is essential when dealing with slow backends where prolonged delays can occur during the read phase. The directive accepts a single parameter which indicates the timeout value. This value can be specified in seconds or using a time suffix (e.g., `m` for minutes, `h` for hours). The timeout settings are crucial for optimizing application performance and should be set based on the expected response times of the backend services. If a connection is idle for longer than the specified duration, it is closed by the NGINX server to prevent resources from being tied up. This directive can be configured in various contexts including `http`, `server`, and `location`. The scope of where the directive is applied can influence how timeouts work in relation to other proxy directives, such as `proxy_connect_timeout` and `proxy_send_timeout`. Making optimal configurations will ensure better resource management and user experience in handling requests through NGINX.
