In fact, the Keepalive_Timeout directive is a powerful tool that can be used to improve the performance and reduce the load of an NGINX server.

By carefully adjusting the Keepalive_Timeout value, you can optimize your application for the best possible performance.

Here are some key takeaways from this guide:

• The Keepalive_Timeout directive controls how long NGINX will keep a Keepalive connection open.
• The default value is 60 seconds.
• A shorter Keepalive_Timeout value can improve performance for short-lived requests, but can increase the number of connections that NGINX has to open and close.
• A longer Keepalive_Timeout value can improve performance for long-lived requests, but can increase memory usage.
• The best Keepalive_Timeout value for your application will depend on the specific application and the traffic patterns.
• You can experiment with different values to find the one that provides the best performance.

In fact, Integrating Nginx and NGINX QGIS Server can provide a number of benefits for your web-based mapping application.

By acting as a reverse proxy, Nginx can improve the performance, scalability, security, and administration of your application.

Here are some of the key takeaways:

• Nginx is a very efficient web server that can significantly improve the performance of your web-based mapping application.
• Nginx is also very scalable, so you can easily add more resources to your server as your application grows.
• Nginx can evenly distribute requests across multiple QGIS Server instances, which can help to improve performance and prevent bottlenecks.
• Nginx can provide additional security for your web-based mapping application by filtering out malicious requests and enforcing security policies.
• Nginx can be used to simplify the administration of your web-based mapping application.

If you are looking for a way to improve the performance, scalability, security, and administration of your web-based mapping application, then integrating Nginx and NGINX QGIS Server is a good option to consider.

In this guide, we have learned about the NGINX Proxy_Redirect directive. We have seen how this directive can be used to change the Location header in a 3xx status message. 

We have also seen how the proxy_redirect directive can be used to change the hostname in the Location header, or to add a trailing slash to the Location header.
