If the user needs to connect to a remote server through
a proxy, this property should be set to a value other than
ProxyNone. Depending on the type of
remote proxy, the user should specify the correct protocol
with this property.
The most common proxy type is ProxyWEBStandard.
Socks 4 and Socks
5 are general proxy protocols, universal to any type
of protocol. Relay is not a real
proxy, but just a 'pipe' or 'redirector'
that listens on a predefined port and when a client
connects to it, opens a predefined destination hostname and
redirects all traffic between the client and the remote
server. A relay proxy is very useful when testing other
protocols. ProxyWEBNtlmAuth is most
recent proxy added and is basically the same as ProxyWebStandard,
except NTLM challenge-response authentication is used with the proxy
ProxyWEBIntegratedAuth is type of proxy where no
username or passwords are sent. Instead, component will try to authenticate using credentials of currently logged in user.
