title: Setting cache-control header for static file serving on nextjs default server
body: <p>I am using the default nextjs server to run my nextjs program by this command <code>next start</code>.</p>
  
  <p>However, I am not able to change the cache-control header for the files under the public folder. </p>
  
  <p>Is there any method to set the cache-control header without setting the Custom Server?</p>
