I have an F on Yslow, because of expired headers.

I have tried all the solutions from similar question and only got partial success.

Here's my .htaccess file:

# BEGIN WordPress

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

</IfModule>
<IfModule mod_expires.c>
### activate mod_expires
ExpiresActive On
### Expire .gif’s 1 month from when they’re accessed (Default algorithm)
ExpiresByType image/gif A2592000
### Expire .jpg’s 1 month from when they’re accessed
ExpiresByType image/jpg A2592000
### Expire .png’s 1 month from when they’re accessed
ExpiresByType image/png A2592000
### Expire .js’s 7 days from when they’re accessed (Alternative algorithm)
ExpiresByType text/js "access plus 7 days"
### Expire .css’s 30 days from when they’re accessed
ExpiresByType text/css "access plus 30 days"
### Expire everything else 1 day from when it’s last modified
ExpiresDefault "modification plus 1 day"

</IfModule>

# Netscape 4.x has some problems...

# MSIE masquerades as Netscape, but it is fine
# BrowserMatch bMSIE !no-gzip !gzip-only-text/html

BrowserMatch bMSI[E] !no-gzip !gzip-only-text/html

# Don't compress images
