Starting with Intelligent Application Gateway (IAG) 2007 Service Pack 1 (SP1), IAG includes an optimizer for publishing SharePoint Products and Technologies with alternate access mapping (AAM). In IAG 2007 SP1, the optimizer uses HTML frame to publish SharePoint via IAG, thus preventing users from bookmarking URLs in SharePoint sites.
In IAG Service Pack 2 (SP2), frames are no longer used by the SharePoint optimizer, and users can use SharePoint bookmarks.
