How to add www to url and redirect?

Question

How can I response redirect from http://domain.com to http://www.domain.com? Code, not Web.config, which doesn't seem to work for me.

Answer 2

Use a 301 redirect to the correct url. Something like this;

Response.StatusCode = (int)HttpStatusCode.MovedPermanently;
Response.RedirectLocation = "http://www.domain.com";

Answer 3

If you are hosting in IIS, then you can set up a HTTP redirect.

IIS6 Redirects

IIS7 Redirects

Information about 301 redirects

EDIT

You could add the following to your Page_Load method:

// Check if page is running under theperfectfajita.com. If not redirect ...
if (!HttpContext.Current.Request.Url.Host.Contains("localhost"))
{
    if (HttpContext.Current.Request.Url.Host.CompareTo("domain.com") != 0)
    {
        HttpContext.Current.Response.Redirect("http://www.domain.com" + Context.Request.Url.PathAndQuery);
    }
}
