Web Connection requires a Web Server for building and testing your application and it supports both Microsoft Internet Information Server and Apache which are the two most popular Web servers. Out of the two IIS is the preferred choice again because it's our primary development platform on which we do primary development, testing and running live applications. Apache is also supported preferrable version 2.2 or later.

You can also work with the Visual Studio Web Server which makes it possible to work without a fully installed Web Server.

Microsoft Internet Information Server (IIS)
Most recent versions of Windows come with a version of IIS that can be used on your local machine.

IIS on Windows is installed as a Windows component and can be enabled through the Programs and Feature Control Panel applet | Windows Components.

There are three Windows versions that do not ship with IIS:

• Windows XP Home
  
• Windows Vista Home Basic
  
• Windows Visat Home Premium
  

Visual Studio Web Server
If you'd rather not install a full Web Server or you are using Windows XP or Vista Home you can also use the Visual Studio Web Server with the Web Connection Managed Module. The Managed Module is a .NET implementation of the Web Connection connector that works with IIS 7 or ASP.NET 2.0 and can also work with Visual Studio's built in Web Server.

This option requires that Visual Studio or Visual Web Developer is up and running so typically you'll use this opt

There are some manual configuration steps involved in using this option which are described here:

Visual Studio Web Server and the Managed Module

Apache for Windows
Web Connection also work with Apache for Windows and provides basic configuration for Apache through the setup and new project wizards. Some custom configuration may be required.

Web Connection works best with Apache 2.2 or later. You can find the latest version of Apache here:
