Method 1

I did this with an HttpModule:

namespace MySite.Classes
{
  public class SeoModule : IHttpModule
  {
    // As this is defined in DEV and Production, I store the host domain in
    // the web.config: <add key="HostDomain" value="www.example.com" />
    private readonly string m_Domain =
                            WebConfigurationManager.AppSettings["HostDomain"];

    #region IHttpModule Members

    public void Dispose()
    {
      //clean-up code here.
    }

    public void Init(HttpApplication context)
    {
      // We want this fire as every request starts.
      context.BeginRequest += OnBeginRequest;
    }

    #endregion

    private void OnBeginRequest(object source, EventArgs e)
    {
      var application = (HttpApplication) source;
      HttpContext context = application.Context;

      string host = context.Request.Url.Host;
      if (!string.IsNullOrEmpty(m_Domain))
      {
        if (host != m_Domain)
        {
          // This will honour ports, SSL, querystrings, etc
          string newUrl = 
               context.Request.Url.AbsoluteUri.Replace(host, m_Domain);

          // We would prefer a permanent redirect, so need to generate
          // the headers ourselves. Note that ASP.NET 4.0 will introduce
          // Response.PermanentRedirect
          context.Response.StatusCode = 301;
          context.Response.StatusDescription = "Moved Permanently";
          context.Response.RedirectLocation = newUrl;
          context.Response.End();
        }
      }
    }
  }
}

Then we need to add the module to our Web.Config:

Find the section <httpModules> in the <system.web> section, it may well have a couple of other entries in there already, and add something like:

<add name="SeoModule" type="MySite.Classes.SeoModule, MySite" />

Method 2

This MSDN page might help you.

Method 3

In general, the performance will be better if you let IIS handle the redirection. To do that, create a new web site with the host header set to example.com, and use IIS Manager to configure the redirection.

Method 4

I think that’s best done with DNS.
