To create clipping portlets that can access content behind firewalls, configure the firewall options for a Web clipping portlet using the Modify firewall options page when you create a Web clipping portlet, or you can add these options later.
Often, it is necessary to use some sort of proxy server to traverse a firewall and access Web content. For example, many corporations require their employees to use a firewall to access Internet content (as opposed to intranet content). What's more, small units within large corporations often have their own firewalls to provide more granular security controls. For these reasons, the Web Clipping Portlet supports the creation of clipping portlets that can access content behind firewalls. You can configure the firewall options for a Web clipping portlet using the Modify firewall options page when you create a Web clipping portlet, or you can add these options later.
Follow these steps to create or modify a Web clipping portlet to use a firewall to access its content:
After finishing these steps, continue, as usual, to save the new or modified Web clipping portlet.
Refer to the Web Clipping help documentation for more information.
