Here in this SharePoint 2016 tutorial, we will discuss what is an alternate access mapping in SharePoint 2016? how to configure alternate access mappings sharepoint 2016 step by step.
Alternate access mapping in SharePoint
Alternate Access mappings in SharePoint allows you to create multiple URLs for the same web application. This will helps users from the internal company network users to access the intranet site by simply using http / https URL and forcing outside the network users accessing it from the internet to use the fully-qualified domain name.
Note: Alternate Access
- Internal users: http://contoso.com
- External users: http://intranet.contoso.com
There are 2 types of Alternate Access Mappings can be configured in SharePoint 2016 they are:
- Internal URLs
- Public URLs
We could say Internal URL is simply an alias for the same site. This means when users type this URL in browser SharePoint redirects them to the Public URL of this Web Application.
This is the other URL configured/mapped to the SharePoint Web Application. This URL completely looks different than the actual URL of the Web Application. However, this URL will be pointed/linked to the same Web Application.
- User requested SharePoint site and it must be resolved in DNS fist and then it will route back to load balancer (or) SharePoint Web Front End Server (SP-WFE)
- IN WFE, IIS will receive the request and look for an IIS binding or an IIS Site
- Once IIS matches one of the Sites then the request will go to SharePoint and render the SharePoint site to the user
Note: The load balancer can any this like F5 / NetScaler / Kemp etc
