Update variable in a content cached template

I have a site with a big menu on top in pagelayout.tpl, in this menu a user can specify a city where it comes from. when a user click on a link of city a custom module it's called and I write a cookie with the id of a node that corresponding of a city, now if a user go to other node/view of a content object I can recover the value of a cookie so I can change information depend on a city that user has chosen.

The problem is if a user change a city because the cookie is updated but the value in template view full no because it's cached from content cache.

I know that I can use this:

{set-block scope=root variable=cache_ttl}0{/set-block}

but there is another way to bypass content cache when I want to read a cookie value?
