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.

Once the connection is closed, the timeout period starts over.

 

The Web server can close the connection at any time.

 

 

Inactivity

The user can close the connection at any time.

 

 

Inactivity
