Using the Protocols page
The Protocols page lets you view and change the selected appliance’s protocol
configuration. You can tune HTTP, NNTP, and FTP timeout intervals; and
configure the appliance to remove HTTP headers from documents to protect site
and user privacy.
▼ Reaching the Protocols page
1 Be sure you are in configure mode. If not, click the CONFIGURE tab.
2 Click the Protocols page button.
The Protocols page is divided into four sections for configuring HTTP, NNTP,
HTTPS, and FTP.
Configuring HTTP
The HTTP section lets you configure the appliance’s handling of HTTP. The
following table describes the section’s options.
