Following htaccess code is available at siteground for Leverage browser caching. My question is that I want to set images expiration time for 1 week and css and scripts expiration time for 2 days. How can I do this? as it is already mentioned in code "now plus 1 month or 1 week after request", but I am not getting it as I am newbie. Can someone please suggest or change below htaccess as per desired? Looking forward for your kind co-operation.

  • Thanks for your input. Default expiration: 1 hour after request ExpiresDefault "now plus 1 hour" What does it mean? As there is already set expiration on images/css/scripts as per desired. But I did not get it ExpiresDefault "now plus 1 hour" – Naeem Sep 15 '14 at 17:00
  • apart from css and images there are other file types too like js,html etc, so default expires headers sets the time for all other file types that we are not defining explicitly.It will increase site performance. – shine Sep 18 '14 at 12:20
  • I have added above code to my htaccess then i checked score on gtmetrix, which increased. But total number of request has been increased from 160 to 200. Why 40 more request has incrased? – Naeem Sep 18 '14 at 19:00
  • is it good to set one week for ExpiresDefault "now plus 1 hour" ? – Naeem Dec 26 '14 at 10:29
