Note: This topic applies to the Framlingham Release.
Guardian enables you to create and make available proxy auto-config (PAC) scripts which determine which IP addresses and domains to access via Guardian and which to access directly.
Guardian supports built-in PAC scripts and custom PAC script templates.
A built-in script is an auto configuration script which you can customize with additional settings such as exceptions.
To use a built-in script:
|1.||Go to Web proxy > Web proxy > Automatic configuration.|
|2.||Select Built-in and configure the following:|
|•||Bypass proxy server for local addresses — Select this option to not use Guardian when connecting to local addresses.|
When selected, this option makes users’ browsers bypass the Guardian proxy if the address is a hostname only, for example:
Browsers will not bypass the Guardian proxy if the address is a fully qualified domain name (FQDN) for example:
|•||Refer to the proxy by domain name — Select this option so that the Guardian proxy uses its domain name instead of IP addresses in the configuration file.|
Before enabling this option, ensure that you have a valid DNS configuration which resolves correctly for this hostname.
This option must be enabled when using Kerberos authentication to use proxy automatic configuration.
|•||Exception domains and IP addresses — In this text box, enter an IP address, IP address range, network address or hostname that users may access directly.|
|•||Exception regular expression domains — Optionally, click Advanced to access the Exception regular expression domains area. In the text box, enter one regular expression domain per line that users may access directly.|
would disable usage of Guardian for
ytimg.com and subdomains such as
www.youtube.com; but not, for example,
|3.||Click Save. Guardian creates the script and makes it available at:
A custom script provides advanced functionality by enabling you to use a script customized to suit your organization.
Tip: You can use the built-in template as starting point for creating a custom script. On the Web proxy > Web proxy > Automatic configuration page, click Download and save the default script to a suitable location. Edit the file to suit your requirements and save it using a different name. See below for how to upload it.
To use a custom script:
|1.||After configuring the custom script, go to the Web proxy > Web proxy > Automatic configuration page.|
|2.||Select Custom script template and click Browse. Locate and select the script and click Upload. Guardian uploads the script and makes it available at:
You define the policy for each interface, by configuring which proxy address the configuration script should direct clients to.
To manage the configuration script:
|1.||Go to the Web proxy > Web proxy > Automatic configuration page.|
|2.||In the Manage configuration script area, from the Interface drop-down list, select the address the configuration script should direct clients to.|
