How to leverage browser caching in All in One SEO

The pageSpeed insight of my website http://www.oratechsolve.com requires tuning for leverage browser caching.

It shows files under wp-content/plugins/.…….js&ver=3.9.2 (24 hours)

How do I increase the expiry date or a maximum age in the HTTP headers for resources?

My .htaccess file has following settings.

# BEGIN WordPress

Header unset Pragma
FileETag None
Header unset ETag

# BEGIN Cache-Control Headers
<ifmodule mod_headers.c>
<filesmatch “\.(flv|gif|jpg|jpeg|png|ico|swf)$”>
Header set Cache-Control “max-age=31536000”
</filesmatch>
<filesmatch “\.(css|pdf)$”>
Header set Cache-Control “max-age=31536000”
</filesmatch>
<filesmatch “\.(js)$”>
Header set Cache-Control “max-age=3153600, private”
</filesmatch>
</ifmodule>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase //
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . //index.php [L]
</IfModule>

## 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 year”
ExpiresByType application/pdf “access 1 year”
ExpiresByType text/x-javascript “access 1 year”
ExpiresByType application/x-shockwave-flash “access 1 year”
ExpiresByType image/x-icon “access 1 year”
ExpiresDefault “access 1 year”
Header set Cache-Control “public”
</IfModule>
