That's because Nginx doesn't match locations on the query string.  I
think you are most likely approaching this wrong anyway.   Judging from
the little you've described, my *guess* is that you need to proxy any
request that can't be mapped directly to an actual file:

location / {
    root /path/to/root;
    try_files $uri @myapp;
}

location @myapp {
    proxy_pass http://blog.foobar.com;
}
