# PingAccess agent for NGINX 2.0 (February 2019)

## Use the NGINX HTTP stack to communicate with PingAccess policy servers

Improved

The PingAccess Agent for NGINX now leverages the built-in, event-driven HTTP stack in NGINX to communicate with PingAccess policy servers. Previously, the agent used its own HTTP client (implemented with libcurl) to communicate with PingAccess policy servers. In certain cases, this architecture lead to poor scalability. By using NGINX's built-in, event-driven HTTP stack, the agent is able to achieve superior scalability over previous versions.
