Remove www from header

[andrewsmd]

I have a site with an ssl certificate. However, the ssl cert is only good for domain.com not www.domain.com. How do I redirect either via IIS or VB in my master page. What I would want to do is just say any request that comes in www.domain.com should go to domain.com. Any suggestions on how to do this? Thanks,

You could query the URL in the global.asax BeginRequest, and redirect if necessary, ie:

Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
If Request.Url.AbsoluteUri.ToLower.StartsWith("http://www") Then
Dim newUrl As String = Request.Url.AbsoluteUri.ToLower.Replace("http://www", "http://")
Response.Status = "301 Moved Permanently"
Response.AddHeader("location", newURL)
End If
End Sub

With IIS7 rewrite module you can add the following to your web.config file:

<rule name="Redirect to non WWW" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www.example.com$" />
</conditions>
<action type="Redirect" url="http://example.com/{R:0}" redirectType="Permanent" />
</rule>

Or use something like urlrewriter.net

I'm using IIS 6 is there a way to do that there, or possibly in dns manager? Thanks for your help.

Not that I know of, but the code I posted will work in IIS6, or a plugin like urlrewriter.net or ISAPI_Rewrite.

Edit: I forgot to add, the code I posted will also work in a master page, but I prefer using Global.asax for this.

Yes, I tried the code and it worked thanks. I just wondered if there was a way to do it in IIS. Thanks though.
