title: How to fix "Setting an expiry date or a maximum age in the HTTP headers"
body: <p>I am using Ftp
  When I run my website on page speed tools, it gives me the following message "Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network."
  How Can I fix this ?<a href="https://i.stack.imgur.com/ZEcNg.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/ZEcNg.jpg" alt="enter image description here"></a></p>
