Hello guys,

I am trying to speed up my site and one of the things is to implement leverage browser caching via htaccess. But i am a bit unsure if this will have negative impact at my forum.

Please look at the htaccess code below and tell me what you think!

## 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>

Well I am not that well acquainted myself with htaccess rules but I do not see anything that looks like an obvious problem.

Worth noting that WordPress tends to append the wp version number to CSS and Javascript files when loading them which, I believe, means they are forced to be re-loaded when the version number changes. I would assume that these htaccess rules will not override that mechanism.

yeah, the only one I would question is the expires of the js…  if you update any wp core, plugins or themes, you might want to force it…

Thank you for the advice guys.

I removed all lines except those below and it seem to work fine. GTmatrix/Pingdom and Google is happy now and giving my site better page speed and yslow rating.

## 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 image/x-icon “access 1 year”

</IfModule>

I really recommed leverage browser chaching and gzip compression via the htaccess file.

Cheers
