In Depth Information
To work with alternate access mapping, you need to be familiar with some terms:
Public URL This is the URL that SharePoint displays in the address bar of the browser and
in all the paths and links generated on the page.
Internal URL This the URL that is presented to SharePoint during the request for a page.
This is often, but not always, the same as the public URL that SharePoint sends back.
Zone Each public URL for a web application is associated with a zone . Zones are just an
easy way to keep track of which public URLs go to which internal URL. When you first create
a web application, the URL used becomes the public URL for the Default zone. The other four
zones are named Intranet, Internet, Custom, and Extranet. The different zones don’t have any
intrinsic differences. The names are just for clarity, and the zones can be used for whatever
you like. Zones are also used to address extended web applications (actually, they’re
primarily used to address extended web applications). In other words, you can take an existing web
application’s content databases and make a new web application (essentially a new IIS Web
Site) that points to those databases; this allows two different URLs to access the same data.

You can create a new public URL by going to the Alternate Access Mappings page and typing
one in order to associate it with an existing web application (and we will do that later). But that’s
not really the point. Public URLs are associated with zones because it is possible that you might
want to offer a web application’s contents to users who require different kinds of security, such
as SSL or anonymous access. These kinds of users can be thought of as being in different zones.
