Excluded page being cached (using .htaccess)

After adding an item to the cart, the page is redirected to /checkout/
which we have added to the exclusion.

However the issue is the /checkout/ page is always show as empty.

(we are using .htaccess)

16:11:07 4997 /checkout/ wpsc_get_auth_cookies: no auth cookies detected
16:11:07 4997 /checkout/ wpsc_is_caching_user_disabled: false

16:11:08 4997 /checkout/ DONOTCACHEPAGE defined. Caching disabled.
16:11:08 4997 /checkout/ wp_cache_maybe_dynamic: returned $buffer

And here is the .htaccess – seems to be duplicated 3 times?
