It is posible, to manage the caching behavoir with my squid.conf, or do all the information (weather to cache the element or not) has to be set in the header by the application (wordpress). I already tried to set the vary header for cookies, but this doesnt leed to a useable configuration. Now, I would unlikely change from squid to varnish.

Most of what the Total-Cache plugin does is setting up proper
cacheability settings on WP outputs. Without it whatever cache you use
will likely not gain you much either way.
Squid, Varnish, Nginx, Apache cache, Browser cache, whatever - can only
work with what they get given.

Back on the cookies issue ... Squid will cache objects regardless of
cookies. Only stripping the cookies on HIT responses as it is supposed
to. The apps I've seen which have cookie issues through Squid are
relying them either for state maintenance with assumptions going against
the GET/POST sementics , or trying to add >64KB of cookies to one message.
