Regarding Cache Control Error

[Vilas]

Dear members,

 

I have tested my site under the below tool.

 

http://siteloadtest.com/

 

But it shows error on all my website pages. Below are some error e.g.

 

• Freshness lifetime (Cache-Control): 14400 sec, 0% of recommended one month.
  

• Freshness lifetime (Cache-Control): 14400 sec, 0% of recommended one month.
  
• Freshness lifetime (Cache-Control): 14400 sec, 0% of recommended one month.
  
• 
  
  • Freshness lifetime (Cache-Control): 14400 sec, 0% of recommended one month.
    

   

  Can anyone know the solution for it?

   

  Thanks in advance.

   

  Regards
