IIS Command: New-WebApplication

The New-WebApplication command in Internet Information Services (IIS) allows users to create a new web application within an existing website. This powerful command provides flexibility and control over the configuration and management of web applications on a Windows server. In this article, we will explore the features and usage of the New-WebApplication command in IIS.

Introduction to New-WebApplication

IIS is a popular web server software developed by Microsoft. It provides a robust platform for hosting websites and web applications on Windows servers. The New-WebApplication command is a part of the IIS PowerShell module, which allows administrators to manage IIS using PowerShell commands.

The New-WebApplication command enables users to create a new web application within an existing website. This is particularly useful when you want to host multiple web applications under a single website, each with its own unique configuration settings.

Syntax and Parameters

The syntax for the New-WebApplication command is as follows:

New-WebApplication [-Name] <string> -Site <string> [-PhysicalPath] <string> [-ApplicationPool <string>] [-Force] [-PreloadEnabled <bool>] [-EnabledProtocols <string>] [-ErrorAction <Preference>] [-WarningAction <Preference>] [-ErrorVariable <string>] [-WarningVariable <string>] [-OutVariable <string>] [-OutBuffer <int>]

Let's take a closer look at some of the important parameters:

  • -Name: Specifies the name of the web application.
  • -Site: Specifies the name of the website under which the web application will be created.
  • -PhysicalPath: Specifies the physical path where the web application's files are located.
  • -ApplicationPool: Specifies the name of the application pool that will be used by the web application.
  • -Force: Forces the creation of the web application, even if it already exists.
  • -PreloadEnabled: Specifies whether the web application should be preloaded in memory when IIS starts.
  • -EnabledProtocols: Specifies the protocols that the web application will support (e.g., "http", "https").

Examples

Let's explore some examples to understand how the New-WebApplication command can be used:

Example 1: Creating a Web Application

To create a new web application named "myapp" under the website "example.com" with a physical path of "C:inetpubwwwrootmyapp", you can use the following command:

New-WebApplication -Name "myapp" -Site "example.com" -PhysicalPath "C:inetpubwwwrootmyapp"

Example 2: Specifying an Application Pool

If you want to specify a custom application pool for the web application, you can use the -ApplicationPool parameter. For example:

New-WebApplication -Name "myapp" -Site "example.com" -PhysicalPath "C:inetpubwwwrootmyapp" -ApplicationPool "myapppool"

Summary

The New-WebApplication command in IIS is a powerful tool for creating and managing web applications within existing websites.
