mod_aclr2Type
About
mod_aclr2 is an Apache web server module that automates serving static content with NGINX as a reverse proxy.
It works by intercepting static file responses in Apache, adding the internal X-Accel-Redirect header, and handing the request back to NGINX for direct file delivery while dynamic requests continue to be processed by Apache.
mod_qos is a quality of service (QoS) module for the Apache web server that implements configurable control mechanisms to prioritize and manage HTTP requests to preserve server resources under load.
It offers limits on concurrent requests per URL or IP, per-second request rate caps, VIP user rules, and request blocking, delay, throttling, and connection dropping to avoid overload and mitigate traffic spikes.
