HTTP Redirects

[gbaughma]

Well, after some searching, I figured out how to do this.

I've been running DotNetNuke (which I *REALLY* like), but I was having some issues... see, DNN installed under a virtual directory /home and that was fine, until I started playing with some subdomains. In other words, it worked fine with a redirect...

http://www.mydomain.com

<%
Response.Redirect ("[URL unfurl="true"]http://www.mydomain.com/home")[/URL]
%>

HOWEVER, when I added a sub-domain....

http://www.mydomain.com

and

http://support.mydomain.com

... that redirect no longer worked. I needed to do some stuff with the HTTP headers. Here's what I did.

<%@ Language=VBScript %>

<%

foo = Request.ServerVariables("HTTP_HOST")

Select Case foo
    Case "[URL unfurl="true"]www.mydomain.com"[/URL]
        Response.Redirect ("[URL unfurl="true"]http://www.mydomain.com/home")[/URL]
    Case "support.mydomain.com"
        Response.Redirect ("[URL unfurl="true"]http://support.mydomain.com/home")[/URL]
    Case Else
        Response.Write "I'm not sure where you want to go.... <a href='[URL unfurl="true"]http://www.mydomain.com'>Try[/URL] This instead</a>"
End Select



 %>

Since DNN takes care of the hosts (it calls it "portals"), this works great, even though both are essentially redirecting to the exact same location.

HOWEVER, you could also use this to redirect to regular pages... for example

support.mydomain.com -->

http://www.mydomain.com/support

foo.mydomain.com -->

http://www.mydomain.com/foo

Just my 2¢
