Authentication For Https Proxy
Proxy-Authenticate – HTTP – MDN Web Docs
The HTTP Proxy-Authenticate response header defines the
authentication method that should be used to gain access to a resource behind a
proxy server. It authenticates the request to the proxy server, allowing
it to transmit the request further.
The Proxy-Authenticate header is sent along with a 407

Configuring Network Setting – Advanced Authentication
You can configure settings for the DNS servers, search domains, gateway, and NICs for the appliance in the tab. You might need to modify these settings after the initial setup if you move the appliance VM to a new host server, or move the host server to a new domain in your network environment. You can also optionally restrict the networks that are allowed to access the appliance.
To configure network settings for the appliance:
Log in to the Configuration Console as the root user.
Click.
In the section, you can modify the DNS name servers, search domains, and gateway settings for your appliance network.
If is left blank, it is auto-populated with the domain of the appliance hostname. For example, if the hostname of the appliance is, the domain is auto-populated with
In the section, you can modify the IP address, hostname, and network mask of any NIC associated with the appliance.
Click the ID of the NIC.
Edit the IP address, hostname, or network mask for the selected NIC.
Repeat the Step 4. a to Step 4. c for each NIC that you want to configure.
(Optional) In the section, do one of the following:
Specify the IP address of each network for which you want to allow access to the appliance. Only the listed networks are allowed.
Leave this section blank to allow any network to access the appliance.
NOTE:After you configure the appliance, changes to your appliance network environment can impact the appliance communications.
Restart the server.
HTTPS connections over proxy servers – Stack Overflow
The short answer is: It is possible, and can be done with either a special HTTP proxy or a SOCKS proxy.
First and foremost, HTTPS uses SSL/TLS which by design ensures end-to-end security by establishing a secure communication channel over an insecure one. If the HTTP proxy is able to see the contents, then it’s a man-in-the-middle eavesdropper and this defeats the goal of SSL/TLS. So there must be some tricks being played if we want to proxy through a plain HTTP proxy.
The trick is, we turn an HTTP proxy into a TCP proxy with a special command named CONNECT. Not all HTTP proxies support this feature but many do now. The TCP proxy cannot see the HTTP content being transferred in clear text, but that doesn’t affect its ability to forward packets back and forth. In this way, client and server can communicate with each other with help of the proxy. This is the secure way of proxying HTTPS data.
There is also an insecure way of doing so, in which the HTTP proxy becomes a man-in-the-middle. It receives the client-initiated connection, and then initiate another connection to the real server. In a well implemented SSL/TLS, the client will be notified that the proxy is not the real server. So the client has to trust the proxy by ignoring the warning for things to work. After that, the proxy simply decrypts data from one connection, reencrypts and feeds it into the other.
Finally, we can certainly proxy HTTPS through a SOCKS proxy, because the SOCKS proxy works at a lower level. You may think a SOCKS proxy as both a TCP and a UDP proxy.
