## EXPIRES CACHING ##
I am using the above code in my .htaccess, but Page Speed Insights, GtMetrix etc are still saying my images not being cached. I tried various different examples posted and nothing is working. My host saids the issue is outside their scope... Any tips or direction to go in to try and diagnose the issue?
I have this code to fix leverage brower cache in my websites for apache, but I think mod_expires is not enabled

But on gtmetrix it still says:
The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources
The syntax of your htaccess file is correct. Please make sure you
place the htaccess file in the right folder (i.e. the root folder of your project)
have the module mod_expires installed and enabled (see how to check if mod_expires is enabled
have set the desired expire time for all of your resources (which resources are ment by "the following resources"? You've set the expire header up to a year for some resources)
I have added Expire Headers to my .htaccess:
## EXPIRES CACHING ##
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
## EXPIRES CACHING ##
But gtmetrix says "There are 30 static components without a far-future expiration date."
I realized that all the files with query string are not included to be cached. For example:
history.js?ver=1.7.1
history.adapter.jquery.js?ver=1.7.1
jquery.form.min.js?ver=3.48.0-2013.12.28
respond.min.js?ver=3.8.1
How can I add caching for those files?
Thanks.
Afaik the query string is ignored by mod_expire
However you may have to include more types, e.g.
ExpiresByType text/javascript "access plus 1 year"
ExpiresByType application/javascript "access plus 1 year"
Also wildcards can help you
ExpiresByType image/* "access plus 1 year"
When i test my website for SpeedTest i'm seeing a lot of expiration not specified error.You can see at this page .
I added this code to my .htaccess file
## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>
## EXPIRES CACHING ##
But nothing changed . Can you give an advice me, for can i specify expiration date for my static files ?
Server : Linux - Apache
i like the html5boilerplate way :
<IfModule mod_expires.c>
ExpiresActive on
# Perhaps better to whitelist expires rules? Perhaps.
ExpiresDefault "access plus 1 month"

ExpiresByType application/json "access plus 0 seconds"
# rss feed
ExpiresByType application/rss+xml "access plus 1 hour"

ExpiresByType application/x-font-woff "access plus 1 month"
ExpiresByType image/svg+xml "access plus 1 month"
ExpiresByType application/vnd.ms-fontobject "access plus 1 month"
# css and javascript
ExpiresByType text/css "access plus 2 months"
ExpiresByType application/javascript "access plus 2 months"
ExpiresByType text/javascript "access plus 2 months"
<IfModule mod_headers.c>
Header append Cache-Control "public"
</IfModule>
</IfModule>
Hope this can be useful to you.

You can use mod_headers to do the trick:
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
Header set Cache-Control "max-age=290304000, public"
</FilesMatch>
Or you can use mod_expires:
ExpiresByType text/html "access plus 1 month 15 days 2 hours"
ExpiresByType image/gif "modification plus 5 hours 3 minutes"
I see you have PHP installed (reference wordpress), so we'll try to diagnose your problem:
restart your apache web server. If you own the apache server (command line access), you can do it like such.
create a phpinfo page. This will allow you to view the apache modules installed. Check for the mod_expires.c module your looking to use (should be able to do a CTL-F (find) request in your browser for mod_expires). If you find it - GOOD! If not, you need to install mod_expires in your apache server. If you own your apache server, you can search on for how to install modules for your specific operating system. If not, you can check with your hosting provider on how to get this module installed. Once installed, proceed.
modify your http.conf entry to include "plus" in your expression
restart Apache again
Test =)
You just need to add:
ExpiresByType application/javascript "access plus 1 year"
Maybe you didn't load mod_expires, so the entire stanza is a no-op. Or, AllowOverride is None and your .htaccess file is not processed.
