DNS via proxy

[iain]

I am trying to work something out.

Consider a private network that connects to the Internet via a proxy server.

When a request arrives at the proxy server that requires forwarding does the proxy perform the DNS lookup and then forward the request, or does it just forward the packet on.

What sort of request?

Generally speaking, as is the case in the network that I'm connected to, whenever I ask for a web page with a domain name my computer connects to the proxy's (the router's) DNS port and requests a lookup, the router then forwards that to its registered DNS server if it's not on the LAN.

Actual HTTP requests pass through.

sorry didnt realise i'd left that bit off. It was HTTP requests i was referring to. So there is no need to consider resolving the dns and all the proxy agent needs to do is to foward it onto the network interface.?
