I am trying to improve the speed

I am trying to improve the speed of http://www.lonesoldiercenter.com. After speaking with @Ashok during a help session he asked me to post this here.

I tried adding the following to the end of the .htaccess file but it resulted in a 500 error

#
# associate .js with “text/javascript” type (if not present in mime.conf)
#
AddType text/javascript .js

#
# configure mod_expires
#
# URL: http://httpd.apache.org/docs/2.2/mod/mod_expires.html
#

ExpiresActive On
ExpiresDefault “access plus 1 seconds”
ExpiresByType image/x-icon “access plus 2692000 seconds”
ExpiresByType image/jpeg “access plus 2692000 seconds”
ExpiresByType image/png “access plus 2692000 seconds”
ExpiresByType image/gif “access plus 2692000 seconds”
ExpiresByType application/x-shockwave-flash “access plus 2692000 seconds”
ExpiresByType text/css “access plus 2692000 seconds”
ExpiresByType text/javascript “access plus 2692000 seconds”
ExpiresByType application/x-javascript “access plus 2692000 seconds”
ExpiresByType text/html “access plus 600 seconds”
ExpiresByType application/xhtml+xml “access plus 600 seconds”

#
# configure mod_headers
#
# URL: http://httpd.apache.org/docs/2.2/mod/mod_headers.html
#

Header set Cache-Control “max-age=2692000, public”

Header set Cache-Control “max-age=600, private, must-revalidate”

Header unset ETag
Header unset Last-Modified

What else can I do? W3TC is installed but I don't know much about what to do with it and I hired someone to help and it broke other things on the site :slight_frown:
