4. If the Web Proxy is deployed in explicit forward mode, edit the settings in Table 16-10.
Table 16-10 Explicit Forward Proxy Mode Authentication Settings
Setting Description
Credential Encryption This setting specifies whether or not the client sends the
login credentials to the Web Proxy through an encrypted
HTTPS connection. To enable credential encryption, choose
“HTTPS Redirect (Secure)”. When you enable credential
encryption, additional fields appear to configure how to
redirect clients to the Web Proxy for authentication.
This setting applies to both Basic and NTLMSSP
authentication schemes, but it is particularly useful for Basic
authentication scheme because user credentials are sent as
plain text.
For more information, see “Sending Authentication
Credentials Securely” on page 363.
HTTPS Redirect Port When you enable credential encryption, specify a TCP port
to use for redirecting requests. This specifies through which
port the client will open a connection to the Web Proxy
using HTTPS.
