How to use Nginx Proxy Manager to achieve fast caching of HTML pages

Introduction:
In modern network applications, fast loading of web pages is an important requirement. In order to improve user experience, we can use Nginx Proxy Manager to quickly cache HTML pages. This article will show you how to use Nginx Proxy Manager to achieve this goal, and provide specific code examples.

Part One: Installation and Configuration of Nginx Proxy Manager

1. Installation of Nginx Proxy Manager
   First, we need to install Nginx Proxy Manager according to the instructions of the official documentation. You can find the installation package suitable for your operating system from the official website and install it according to the instructions.

2. Configure Nginx Proxy Manager
   Open the configuration file of Nginx Proxy Manager and configure it according to your needs. You can set parameters such as cache size and cache path to meet your specific needs. An example configuration snippet looks like this:

   proxy_cache_path /path/to/cache levels=1:2 keys_zone=my_cache:10m max_size=10g inactive=60m use_temp_path=off;

   In the above example, we set up a cache path named "my_cache" with a maximum cache size of 10GB and a cache time of 60 minutes.

Part 2: Configure Nginx reverse proxy

1. Configure Nginx reverse proxy
   In the configuration file of Nginx Proxy Manager, We need to configure a reverse proxy to cache HTML pages. An example configuration fragment is as follows:

   server {
       listen 80;
       server_name example.com;
   
       location / {
           proxy_pass http://backend_server;
           proxy_cache my_cache;
           proxy_cache_valid 200 5m;
           proxy_cache_use_stale error timeout updating http_500 http_502 http_503 http_504;
           proxy_cache_revalidate on;
           proxy_cache_lock on;
       }
   }

   In the above example, we configured a server that listens on port 80 and forwards all requests through the reverse proxy (proxy_pass) to the server named "backend_server" backend server. We also configured the cache name "my_cache" and set a cache policy with a validity period of 5 minutes.

2. Restart Nginx Proxy Manager
   After the configuration of Nginx Proxy Manager is completed, we need to restart Nginx Proxy Manager to make the configuration take effect. You can run the following command to restart:

   sudo systemctl restart nginx

Part 3: Test the caching effect

1. Visit the web page
   Now, you can access it through your browser Your website, load your HTML page normally.

2. Check cache
   After your webpage is accessed for the first time, you can confirm whether the webpage is cached by checking the files in the cache path. For example, if we set the cache path to "/path/to/cache", you can run the following command to view the cache files:

   ls /path/to/cache

   If you see something like "example.com/index.html" file, it means that your web page has been successfully cached.

3. Test caching effect
   Now, close the browser and visit your page again. You will find that web pages load faster because Nginx Proxy Manager returns web pages directly from the cache instead of requesting the backend server.

Conclusion:
By using Nginx Proxy Manager, we can easily achieve fast caching of HTML pages. This article provides detailed steps for installation, configuration, and testing, and provides specific code examples to help you get started quickly. Please adjust the sample code according to your specific needs, and perform more configuration and optimization according to the official documentation. I wish you success in implementing fast caching of HTML pages!
