Expires & mod expire

[sendandreturn]

Hi,

In the htaccess of my subfoldered WP blog, I have this in the htaccess.


ExpiresActive On
ExpiresByType image/gif A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/png A2592000
ExpiresByType text/js M604800
ExpiresByType application/javascript M604800
ExpiresByType application/x-javascript M604800
ExpiresByType text/css M604800

and I don't get a 500 error when I load the site, which hints at my hosts supporting mod expire, it does bomb out with a 500 error if I try to do anything mod header related like ET tags...

However Page Speed from Google still swears blind I am not taking advantage of browser caching..I do have a page speed of 87/100 which is nice! but it would be good to squeeze out some more...

Any ideas why Page Speed thinks I am not browser caching?

Thanks..
M.
