Extend a Web application: - This is a very interesting feature of SharePoint. Suppose we have 1 web application and, we want to use 2 different URL for different audience or with different authentication. Then we need to extend a web application in to a new zone. We call it "Extend a Web application".

Now you must be wondering, How to do it?

1. We need to create a separate Internet Information Services (IIS) Web site to serve the

    same content, but with unique URL and authentication type.

2. An extended web application can use up to 5 network zone (Default. Intranet, Internet, 

    Extranet, Custom). We can use two different zones for same application to providing

    different authentication.

3. We need to identify for which authentication we would use into extended web  
     application.

    Let’s choose it Windows-classic Authentication.

    How to extend a web application with Windows-classics Authentication step by step?

1. The user must be member of farm administrator SharePoint group and the member of  

    local administrator group on the computer running Central Administration.

2. Then click on "Manage Web Applications"

3. Then select the web application that you want to extend.

    NOTE: Generally this field not set, unless you want to configure two or more web     

     sites same port number on the same server and DNS has been configured to multiple 

     server names to the same server. 

    e). in the "Path" section, this field is populated with the current path of that Web site.
