Link translation in Web publishing

Web pages returned from a Web server published by a Forefront TMG Web publishing rule may include links containing internal names of computers or Web sites and internal paths to Web content. Because external clients cannot resolve these internal names, these links will be broken unless the internal names are replaced by the public names of published Web sites. Forefront TMG includes a built-in Web filter named Link Translation Filter, which uses mappings to translate internal names in links on Web pages to publicly resolvable names. Each mapping translates an internal URL (or part of a URL) to a public equivalent. For example, a mapping can translate the internal URL https://team to the public URL https://www.team.contoso.com. Link translation mappings are stored in tables called link translation dictionaries.

When link translation is enabled for a Web publishing rule, a default link translation dictionary is automatically created for each public name of the rule that does not contain a wildcard character (*).

Forefront TMG includes link translation support for all published Web content, including support for Web publishing rules that publish servers running Microsoft Exchange Server and Microsoft Office SharePoint® Portal Server. Link translation is not applied to rules that publish FTP servers over HTTP.
