Add the following lines to enable the module and set basic parameters:
LoadModule ah_64_d_module /usr/lib/apache2/modules/mod_ah_64_d.so
Ah64DEnable On
Ah64DMaxConnections 1000
Ah64DTimeout 30
Save the file and restart Apache to apply the changes:
sudo systemctl restart apache2
Advanced Configuration
For more advanced configurations, you can customize various parameters to optimize performance and security. Some of the advanced settings include:
| Parameter | Description | Default Value |
|---|---|---|
| Ah64DMaxConnections | Maximum number of concurrent connections. | 1000 |
| Ah64DTimeout | Timeout for idle connections. | 30 |
| Ah64DLoadBalance | Enable load balancing. | Off |
| Ah64DSecurityLevel | Security level for request handling. | Medium |
To enable load balancing, for example, you can add the following lines to your configuration file:
Ah64DLoadBalance On
Ah64DLoadBalanceMethod round-robin
This configuration will distribute incoming traffic evenly across multiple servers using the round-robin method.
🔍 Note: Always test your configuration changes in a staging environment before applying them to a production server to avoid any disruptions.
