Management of proxied servers through a REST-like [API interface](https://en.angie.software//angie/docs/configuration/modules/http/http_api.md#api-config) for dynamic configuration; the visual monitoring console [Console Light](https://en.angie.software//angie/docs/configuration/monitoring.md) can also be used to manage the server through a browser. Load balancing considering the [average response time](https://en.angie.software//angie/docs/configuration/modules/http/http_upstream.md#u-least-time) from proxied servers with a [configurable smoothing factor](https://en.angie.software//angie/docs/configuration/modules/http/http_upstream.md#u-response-time-factor). Feedback-based load balancing, which selects servers based on the value of a variable; it is assumed that this value comes from the servers themselves, transmitting CPU load or other metrics. Checking the availability of proxied servers by sending periodic [test requests](https://en.angie.software//angie/docs/configuration/modules/http/http_upstream_probe.md#u-upstream-probe). Additional sticky binding mode [sticky learn](https://en.angie.software//angie/docs/configuration/modules/http/http_upstream.md#u-sticky), allowing sessions to be detected and remembered in shared memory. Conditional [binding of client connections](https://en.angie.software//angie/docs/configuration/modules/http/http_upstream.md#u-bind-conn) to a connection with the proxied server, which also allows for NTLM proxying. Allows responses to be placed [in different locations](https://en.angie.software//angie/docs/configuration/modules/http/http_proxy.md#proxy-cache) based on their properties. ## Support and Services We offer [standard](https://en.angie.software//support/index.md) support during business hours and 24/7 [enterprise](https://en.angie.software//support/enterprise.md) support.
