Apache caching with .htaccess problem (incorrect Date header?) - apache

Question

I am using .htaccess to cache the js / css / etc files on the website. Everything works fine, but for some reason my pages get cached, too. I looked into the headers, and it works like this:
Browser requests a page http://poko.lt/up
Server responds with 301 to http://poko.lt/up/ (with Date and Last Modified headers equal to current time)
Browser requests http://poko.lt/up/
Server responds with the page, and with Date and Last Modified headers equal to my last forced refresh (like, yesterday), but Cache-control header is fine (max-age=0)
I get the old version of the page :/
My .htaccess looks like this:
# Turn on Expires and set default to 0
ExpiresActive On
ExpiresDefault A0
# 1 YEAR
<FilesMatch "\.(jpg|jpeg|png|gif|svg|eot|ttc|ttf|otf)$">
ExpiresDefault A29030400
Header append Cache-Control "public"
Header unset Last-Modified
Header unset ETag
FileETag None
</FilesMatch>
# 2 WEEKS
<FilesMatch "\.(css|js|swf)$">
ExpiresDefault A1209600
Header append Cache-Control "proxy-revalidate"
Header unset Last-Modified
Header unset ETag
FileETag None
</FilesMatch>
# NO CACHE
<FilesMatch "\/$">
ExpiresDefault A0
Header append Cache-Control "proxy-revalidate"
Header unset Last-Modified
Header unset ETag
FileETag None
</FilesMatch>
And, one can test it with the website http://poko.lt (the three red icons in the top middle of the page are the ones causing the problems). I am using FF4, and checking headers with Firebug.
