Firewall Object - Properties

HTTP Service Proxy Settings

Additional controls of specific network traffic can be put into place by allowing or limiting commands unique to the various protocols.

The following dialog provides options to fine tune Internet Browser (HTTP) service capabilities.

HTTP Service Proxy Settings dialog

Protocol Commands Policy:
Allow unrestricted communication

This option provides full compatibility with any HTTP application service by disabling the features of the service proxy.  All HTTP commands will be processed without restriction by the Firewall Object.

Allow only commands that read data from the server

This option is an easy and safe way to provide "read-only" capabilities for clients and exclude HTTP operations that would post or put to other servers or hosts.  This service proxy would be best applied to a rule allowing outbound connections from internal clients to open HTTP sessions with external hosts, yet restrict them from writing to or uploading information to those external hosts.

Allow only specific commands

This option gives granular control over common HTTP commands as defined in the Allowed Commands frame.

Allowed Commands:

By checking or unchecking items on this list the processing of certain HTTP commands are allowed or disallowed.

Return custom response when a command is denied:  

When ever the Firewall Object rejects an HTTP command according to the settings of this rule, a custom message is returned to the requester's browser window.  This message is unique and specifically applied for this rule only.

This user-definable field contains the HTML content to be displayed to a user when there is a violation of the HTTP commands rule.   The administrator simply needs to edit the text between the HTML control parameters and save the changes.

Replace Server Banner

This check box and the associated text box provide a method to update the Firewall Server Window with a appropriate display message that can be used for alerting the user to the status or condition of the Server.
