## Application Integration
### Asynchronous Mode Nginx\* with QAT
NGINX\* with asynchronous mode for Intel® OpenSSL QAT Engine provides
significant performance improvement with QAT acceleration.
The asynchronous fork of NGINX\* can be found at the following Github\*
repository:
* [Intel® QuickAssist Technology (QAT) Async Mode NGINX\*](https://github.com/intel/asynch_mode_nginx)
Follow the below link on how to enable Async mode Nginx\* with QAT Hardware and software
Aceeleration using best known configuration.
[Async mode for Nginx\*](https://intel.github.io/quickassist/qatlib/asynch_nginx.html)
### NGINX\* QUIC with QAT
Experimental QUIC support for NGINX\* with Intel® QAT Engine for
BoringSSL\* Library can be found [here](https://www.intel.com/content/www/us/en/content-details/737522/experimental-quic-support-for-nginx.html)
### HAProxy\* with QAT
HAProxy\* is a free, very fast and reliable reverse-proxy offering high availability,
load balancing, and proxying for TCP and HTTP-based applications.
Follow the instructions from HAProxy [Install](https://github.com/haproxy/haproxy/blob/master/INSTALL)
to build and install Haproxy. Use `USE_PTHREAD_EMULATION=1` option in the make command which improves performance
utilizing HAProxy's much lighter locks replacing OpensSL\* Pthread locks.
Add the following options along with other standard settings in the
HAProxy\* [Configuration File](https://www.haproxy.com/documentation/haproxy-configuration-manual/latest)
to utilize QAT Acceleration.
```bash
ssl-engine qatengine algo ALL
ssl-mode-async
```
