How to setup Typo3 so client-side caching is enabled?

I have found the following page on the matter: http://typo3.org/development/articles/using-cache-control-headers-in-typo3/page/3/

But enabling config.sendCacheHeaders does not seem to give me what I want..

There are no plugins/USER_INT's on the page, or COA_INT's..

These are my settings, am I missing something?

config {
    no_cache = 0
    sendCacheHeaders = 1
    cache_period = 86400
    cache_clearAtMidnight = 1
}

And this is what I get:

Cache-Control:private

I'm using Typo3 4.5

Forgot to check back here. The problem is solved, I think the cache didn't work because I was still logged into the Typo3 backend. Logging out of Typo3 solved this. Doh!
