Manage alternate access mappings

Each Web application can be associated with a collection of mappings between internal and public URLs. Both internal and public URLs consist of the protocol and domain portion of the full URL (for example, https://www.fabrikam.com). A public URL is what users type to get to the SharePoint site, and that URL is what shows up in the links on the pages. Internal URLs are in the URL requests that are sent to the SharePoint site. Many internal URLs can be associated with a single public URL in multiserver farms (for example, when a load balancer routes requests to specific IP addresses to various servers in the load-balancing cluster).

Each Web application supports five collections of mappings per URL; the five collections correspond to five zones (default, intranet, extranet, Internet, and custom). When the Web application receives a request for an internal URL in a particular zone, links on the pages returned to the user will have the public URL for that zone.

To manage alternate access mappings:

1. On the top navigation bar, click Operations.

2. On the Operations page, in the Global Configuration section, click Alternate access mappings.
