476 Part VI: Administration of Microsoft Office SharePoint Portal Server 2003
The Microsoft SharePoint Portal Server Search (SharePointPSSearch) service consults
the alternate access setting entries when crawling a document. If the URL of the
document matches one of the mapping entry URLs, the URL is replaced with the mapping
ID for the entry. When the search result is displayed, the mapping ID is replaced
by the appropriate URL if the user is requesting the document from an access point
listed in the alternate access setting entries. If there is no appropriate alternate mapping,
the search results display the default URL. Figures 17-11 and 17-12 show the
same search results for a query. Note the status bar at the bottom of each, which
shows that the appropriate alternate address URL has been placed for the link.

When defining alternate access, every entry must have a default URL. Each entry
can have additional alternate access methods for either intranet, extranet, or custom
access. Each URL must be different from all other URLs. These mappings are stored
