How to Add Far Future Expires Headers to Your WordPress Site

You are here: Home / Web Development / Site Optimization Tips / How to Add Far Future Expires Headers to Your WordPress Site

Last updated: August 29, 2013





Few weeks ago I wrote on how to optimize your WordPress site for better performance which has some tips and tricks on how to speed up a WordPress Site. I received a few requests to elaborate on some of the points as not all of them are obvious changes. In this article I have explained how you can add far future expiry header to your image, css and javascript files to speed up your site.

Adding expires headers do not affect the site load time for a first time visitor but you will be surprised how much the page load time decreases (faster page load) for subsequent page views/return visits from that visitor. Expires header specifies a time far enough in the future so that browsers won’t try to re-fetch images, CSS, javascript etc files that haven’t changed (this reduces the number of HTTP requests) and hence the performance improvement on subsequent page views.

You can now use our WP Far Future Expiration Plugin to do this task easily

If your server is Apache (most web servers), you can use the ‘ExpiresDefault’ directive to set an expiration date relative to the current date.



ExpiresDefault "access plus 2 months"

This sets the expiry date of the file 2 months into the future from the current time. The following values can be used to specify the time period:

  • years
  • months
  • weeks
  • days
  • hours
  • minutes
  • seconds

eg. ExpiresDefault “access plus 14 days”

To add expires header to the image, CSS, javascript files add the following to your .htaccess file
#Expire Header
<FilesMatch "\.(ico|jpg|jpeg|png|gif|js|css|swf)$">
ExpiresDefault "access plus 2 hours"
</FilesMatch>

or
# Expire images header
ExpiresActive On
ExpiresDefault A0
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/ico A2592000
ExpiresByType text/css A2592000
ExpiresByType text/javascript A2592000

A2592000 means 1 month in the future (60*60*24*30=2592000)

Keep in mind that when you use expires header the files are cached in the browser until it expires so do not use this on files that changes frequently. If you change/update a file that has a far future expiry (eg. CSS or javascript files) then you should rename that file and use the renamed version so the browser doesn’t fetch the old file.

Video Tutorial (Adding Far Future Expiry Header)

Removing ETags

According to Wikipedia – “An ETag (entity tag) is an HTTP response header returned by an HTTP/1.1 compliant web server used to determine change in content at a given URL. When a new HTTP response contains the same ETag as an older HTTP response, the contents are considered to be the same without further downloading.”

ETags were added to provide a mechanism for validating entities that is more flexible than the last-modified date but If you’re not taking advantage of the flexible validation model that ETags provide, it’s better to just remove the ETag altogether. Removing the ETag reduces the size of the HTTP headers in the response and subsequent requests thus improving site performance.

Add the following to your .htaccess file to remove ETags:

FileETag none

These tweaks can dramatically improve the performance of your site even though they are minor and doesn’t take that long to apply. I have seen a 20% speed improvement on my page loads just by adding these tweaks. My home page used to take around 5 seconds to load but then it dropped to around 3 seconds after these tweaks. Below is a screenshot of YSlow:

    The commenting system stripped out the code from my examples.

    Basically, just paste this line:
    ExpiresActive ON

    before you specify the expiration timeframes if you’re using the FilesMatch method as mentioned in the post on this page.

    @Mukesh, Try a 1 year value rather than 1 month. YSlow sometimes doesn’t catch it if that value is not long enough.

    Thank you, thank you! Clear concise instructions. I’m just setting up a new site and after testing my page speed saw I should change my set expires. I remember this coming up on an older site a few years ago and not being able to find HOW to change this, when YSlow was telling me I SHOULD change it.

    I was getting a grade B, 81% so lets see what kind of improvement I get after implementing this.

    Thank you for a great explanation of thees too issues. It made me understand what’s going on much better.

    I also discovered that there is a fantastic plugin actually doing the job for you.

    Now, I’m not a big fan of plugin’s – to many only slow down your site – but since this particular one does so much more good for your seo, than just this, I believe it’s worth the(eventual) loss of speed to install it anyway.

    I also found some additional great help on speeding up your site at Yahoo.com

    Ones again, thank you for your article. I’ll sure come back and see what else you have to tell.

    When I page the above code in .htaccess I am getting internal Error, however I have managed to get my scores to 70% which is C Grade. Still I have some issues left like use a CDN, Add Expires Headers, Compress Componenets with gzip and Reduce DNS lookups.

    I am still figuring out how to solve this problems.. I am using cloud hosting from nethosting. anything to be done in WHM.

    Required your suggestion.

    Thanks

    @Friv, you will most likely need to change the time to more than 1 year for the tool to recognize it but you can be sure that your images are being cached by browsers for that 2 month (when you browse various pages of your site you will notice the difference)

  40. Friv says:
    April 28, 2011 at 2:42 am

    Thanks!
    I am finding it.

  41. admin says:
    April 11, 2011 at 9:45 pm

    @Nathan, You can load one of your site’s page with images few times and get an average page load time. Then apply this technique and record a few more page load time after. Comparing these two sets of data should give you an indication.

  42. Nathan says:
    April 11, 2011 at 6:25 am

    Its not showing up under any testing system. How can i be sure that I have everything right?

    Thanks

    really, a whole year! OK. many thanks for the help, appreciate it.

  47. admin says:
    April 5, 2011 at 10:47 pm

    @Nathan, You will need to set the time to 1 year or more to get the score from Yslow but it doesnt’ mean its not working. Your static content will still be cached for 2 months and you will see an increase in performance.

  48. nathan says:
    April 5, 2011 at 7:29 am

    Ive placed the first code in my htaccess file and changed it to 2 months, but Yslow still says I have nothing? Any suggestions. If you need any more info just say.

    Thanks

    Some hosting providers do not allow the “expires header” for their shared hosting accounts. This is probably why its giving a 500 error when you try to use them.

  50. Scott Lincoln says:
    March 10, 2011 at 3:19 pm

    I was wondering will this method of future expires adversely affect my project wonderful ads?

    Also, I am using Godaddy hosting on my WordPress/Comicpress based site. So I accessed my htaccess file from my GoDaddy file manager, I checked the htaccess file and clicked edit, but every time I saved the file after adding either script version I immediately got a 500 error message on my site. When I deleted the new scripting and saved it, the error disappeared and the site functioned normally. The only other scripting in the htaccess file is for Super Cache and a couple other plugins… Is there a certain place to paste the script or certain tags etc?

    I’d really like to be able to have jpgs and pngs cache since I have quite a few images on my site. Am I missing something?
