http acel mode and frequently changing pages

I have squid running in acelerator mode in front of an apache server
on our main web server. I have compiled in the expires module in
apache and on a page that changes frequently have the following in
the .htaccess file:

ExpiresActive On
ExpiresDefault A300

However, it is still often over 24 hours before changes to this web
page are seen. Does anyone know why this would be happening?
