Aditya:For a firewall to work at application level, you would (90% of
the time) need to proxy the traffic through it for best results. So,
we can call it 'application level firewall' or 'intelligent proxies'.

Take a look at below links which would throw some moe light on this topic.

It would be interesting to know Which firewalls have you worked on ?
Any Application level firewall ?

Thanks,
