Pattern Matching Redirect IIS 6.0

[dertyfern]

I'm using II6 and I'm undergoing a url rewrite project to create friendly urls from existing ugly ones that use a query string.

Problem is: I've got hundreds of old urls which have SE rankings and I want to preserve their "history". Is there any way to permanently redirect them all using pattern matching with IIS 6?

Thanks in advance for any input.

Think I may have found an answer to my question--would this work adequately while preserving history?:

<script runat="server">
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location","/new-page.asp");
}
</script>

Anyone? I'm certain there must be someone who's dealt with this.

Got the answer. Thanks for all the help out there. If anyone need to know who this is done properly please don't hesitate to sticky.

Did you consider perhaps that nobody else knew the solution? Rather than throw out the sarcasm why not publish the solution for future readers having the same issue? :)
