What is proxy authentication?
Proxy authentication refers to a method of authentication used by a web browser to access a remote server.
A proxy server receives incoming requests from the browser and attempts to authenticate the user using a form of authentication that is specific to that server. After successfully authenticating the user, the proxy server sends the request on to the remote server. A few common examples of proxy authentication include:
HTTP authentication using Basic HTTP authentication, NTLM authentication, or Kerberos authentication. HTTPS authentication using mutual TLS authentication. In order to set up a proxy server for authentication, you need to provide a list of proxy credentials for the proxy server. The proxy credentials are entered into the web browser when the browser accesses the proxy server. If the credentials are valid, the web browser is given access to the remote server. Otherwise, the browser is given access to the proxy server.
You can use a proxy server to help secure your website by creating a unique login session for each client. This way, if a hacker hacks into the remote server, the attack will not compromise your users' login sessions. In addition, you can provide a single login session to clients, including employees and partners, who must be able to log into your website.
Important. We recommend that you do not use an HTTP proxy for authentication if your site is accessed by users behind a corporate firewall. For example, the corporate firewall may block HTTP requests that contain the credentials of a proxy server.
Using an HTTP proxy for authentication is generally considered a best practice for large organizations with a very large number of users, as it provides a method to authenticate the user once and then reuse that login for all their requests. You can use any of the following technologies: What does it mean to "use" a proxy server? Proxy servers are generally used to secure access to remote servers. When you use a proxy server for authentication, you are using it to secure access to a remote server. Therefore, you can say that you "use" the proxy server when you are accessing the remote server through the proxy server.
It's important to understand that proxies are not secure. Proxy servers can be used for logging in to remote servers, but they cannot be used to encrypt or otherwise secure the connection between the web browser and the remote server.

What is a forward proxy?
When you set up your web site, you're automatically given a name and address.
When someone accesses your website, the site's computer gets information about the device accessing it. In the case of a browser, it includes its IP address.
This is important because when people visit your site, it doesn't know where they are. So if someone is using a proxy server, it can access your website through this server and then relay the visitor information back to your site.
By using a proxy server, your website visitors will appear as if they are on the Internet from a different place. It also works the other way: if someone visits your website through a proxy server, it can send the IP address of the server's owner to your website, which is useful for identifying who owns the server. For example, if someone is using a proxy to hack into your web site and view all your files, that person could be traced by their IP address.
What are proxies used for? Websites need to be accessible to all IP addresses on the Internet. But sometimes, you or your visitors may have had their computer hijacked. This could be done with malicious software such as Trojans. Other people could hack into your computer through a public network such as a library.
The main reason people use proxies is to make their hijacked or infected computer appear as if it is on the Internet from another IP address. For example, a hacked or infected computer could be accessed through the Internet from another country. You can do this by setting up a proxy on your computer and accessing the proxy server that connects to the hacked or infected computer.
How do I set up a proxy? If you don't have a proxy, it's easy to set one up: on your Windows computer, go to the Control Panel and open Network and Sharing Center. On the left side, click on Internet Protocol Version 4 (TCP/IPv4), which will open a Properties dialog box.
Click on the Advanced button. In the TCP/IPv4 Properties dialog box, click on the Properties button in the bottom-right corner. Under Internet Protocol (TCP/IP) 4 Properties, enter the following IP address in the Proxy address:port entry: 0.1:80 Click OK.
How to set up a forward proxy?
This example from Proxying the web is one way of doing it, but I think another better way is to get a Squid proxy running which comes with most Linux distros.
In an apache configuration:
ServerAlias example.com ProxyPass /. . All other websites will now be proxied to 127.0>1:8001 (the proxy server is a dummy web server listening on port 8001).
