proxy_cache_bypass and proxy_no_cache

[amodpandey]

I did this ( my cookie name is cahe )

    map $cookie_cache $dont_cache {
        0 1;
        1 0;
    }

proxy_cache_bypass    $dont_cache;
proxy_no_cache        $dont_cache;

But the first request which does not have the cookie is getting cached.
