– HTTP over Proxy Settings: The settings required to communicate over a proxy
network using HTTP. These settings apply when Automatic or HTTP over Proxy
connection methods are selected.
Hostname: The name of the proxy host.
TCP Port: The network port number for the TCP network service on the proxy
host.
Username:
Password: The username and password for logging on to the proxy host.
Enable persistent proxy connections: Specifies whether the Digi device should
attempt to use HTTP persistent connections. Not all HTTP proxies correctly handle
HTTP persistent connections. The use of persistent connections can improve
performance of the exchange of messages between the device server and remote
management server, when that connection is HTTP/proxy. The reason for this is that
the same HTTP connection can be reused for multiple consecutive HTTP requests
and replies, eliminating the overhead of establishing a new TCP connection for each
individual HTTP request/reply, then closing that connection when the request is
complete.
