The application customization is all about UAG's content parsing, part of which is the Host Address Translation (HAT) process. If you don't recall, this is the mechanism that iterates through web pages that UAG delivers to its users, looks for links and rewrites the URLs. This is done, of course, for every web application, but UAG also includes some specific templates for specific applications. For example, Outlook Web Access requires very specific changes to be made to the HTML code that is sent to the user and so do SharePoint and Microsoft CRM 4. In fact, you can take a look at this yourself by opening the file, HTTPS_WhlFiltAppWrap_ForPortal.xml
, located in C:\Program Files\Microsoft Forefront Unified Access Gateway\von\conf\WizardDefaults\AppWrapTemplates
.
Don't be tempted to change this file, though! You can create a custom file to perform your own changes to data coming from an application, but this is beyond the scope of this book. It is discussed...
