That’s it for all the buttons and settings under Manage Web Applications. Now on to the only
other settings link in the Web Applications subcategory, Configure Alternate Access Mappings.

Alternate access mappings were covered in detail in Chapter 10. This setting is also located
under the Farm Management subcategory in the System Settings category. Alternate access
mappings are generally associated with web applications. Here’s a basic idea of how they work.
SharePoint uses internal and public URLs for its addressing. Internal URLs are those the
SharePoint server can accept, which give users access to a particular web application. Public
URLs are ones that the SharePoint server returns to a user (showing up in the browser and
the URLs for search results) when they access a web application using a particular Internal
URL. SharePoint has five public URLs: Default (used by the web application for its real URL),
Intranet, Internet, Custom, and Extranet. Each public URL is considered a zone. Remember that
when you extend a web application, its address uses one of the zones available for the
originating web application. This limits the number of extended web applications per original web
In addition to viewing and editing the zones available for a selected web application, you can
also add additional internal URLs and map to external resources (Figure 11.12). When you add
an internal URL, you need to specify a public URL to which it will resolve. If you can, reuse an
existing public URL to conserve zones.
Mapping to an external resource is one of those settings that is primarily a hook for
SharePoint Server 2010 or a third-party product, because it is meant to be used to mask the URL
of an external resource. Setting up an external resource requires a resource name and URL.
Once you create the resource, it’s treated like a web application, in that it gets its own zones and
can have additional internal URLs.
