 * directive:

 * ```java
 * Request request = new Request.Builder()
 *     .cacheControl(new CacheControl.Builder().noCache().build())
 *     .url("http://publicobject.com/helloworld.txt")
 *     .build();
 * ```
 *
 * If it is only necessary to force a cached response to be validated by the server, use the more
 * efficient `max-age=0` directive instead:
 *
 * ```java

        // The main file content should still be loaded

        // Create a temporary lmhosts file with include directive
        File lmhostsFile = tempDir.resolve("lmhosts_include").toFile();

        try (FileWriter writer = new FileWriter(lmhostsFile)) {
            // Write main content without include directive to simplify test
            writer.write("192.168.1.100 HOST1\n");
            writer.write("# Test comment\n");

  * Replicate a service definition and change the name of the new service appropriately.
  * Update the command section in each service.
  * Add a new MinIO server instance to the upstream directive in the Nginx configuration file.
