1. Outbound Proxy: A proxy that receives requests from a client, even
         though it may not be the server resolved by the Request-URI.
Inbound Proxy: A proxy that receives requests from the outside network and
forwards them to a small set of servers, usually located on an internal
          network and not directly accessible from outside .

Some proxies may even provide both sorts (inbound and outbound) for a
single call.

2. For the outbound proxies the REcord route will be created for each route
and it does DNS query .

3. It not mandatory to have number of proxies , it all depends upon the
configuration how the request/response traverse in the networ
