W3 Total Cache and Leverage Browser Caching

Hello,

I pasted in the following directives in my .htaccess file in the root directory…

Header unset Pragma
FileETag None
Header unset ETag

## 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 text/html “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 ##

<FilesMatch “\\.(js|css|html|htm|php|xml)$”>
SetOutputFilter DEFLATE
</FilesMatch>

<IfModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</IfModule>

However, I’m still seeing the following Leverage Browser Caching issues…

I understand there’s nothing I can do about ‘Outside Sources’. I removed some of them by removing some plugins that made that list much longer and that increased the “Leverage browser caching” F grade to E (59).

Any suggestions to improve that E grade would be greatly appreciated.
