Proxy authorization is a setting that you enable in a policy to require that ETP Proxy authorize
connections from the on-premises proxy in a proxy chaining configuration. This setting adds
the Proxy-Authorization header to these connections. The Proxy-Authorization header contains
proxy credentials that are used to authenticate the on-premises proxy. ETP Proxy validates these credentials
before it allows connections from the on-premises proxy.
To set up proxy authorization, you must:
Configure proxy credentials. This process
involves creating a username and password. For instructions, see Create a proxy credential.
Configure these proxy credentials in the on-premises proxy. For instructions on
configuring these credentials in Squid, see Configure Squid to forward traffic to ETP Proxy.
Select to trust the X-Forwarded-For header in a policy. For instructions, see Enable a full web
Enable the Proxy Authorization setting in the policy. For instructions, see Enable a full web
proxy or Enable proxy authorization
Note: Proxy authorization uses a basic authentication scheme. The credentials in the proxy
authorization header are base64 encoded. HTTPS and TLS further secures these credentials in
In situations where ETP Proxy cannot validate the request, a browser error message appears.
If authentication fails, a browser error message indicates that authentication
If proxy authentication is enabled in a policy and there are no proxy credentials
configured, a browser error message indicates that proxy authentication is required.
If proxy authorization is not enabled in a policy for a proxy chaining
configuration, requests are accepted by ETP Proxy as long as they come from a known location.

The 407 Proxy Authentication Required is similar to 401 Unauthorized. A 401 Unauthorized Error is an HTTP status code that indicates that the server received an unverified request. The only difference is that authorization needs to be done by a proxy.
