Canonical name redirects in Godaddy?

问题

I have a website "mywebsite.com" and I would like to do a 301 redirect of "http://mywebsite.com" to "http://www.mywebsite.com" (for the usual SEO purposes).

I am running IIS7, however there is an ISA server firewall in front of the site, which seems (as per this article, though his solution did not work for me -- http://mrvirtual.de/2009/07/04/url-rewrite-through-isa-server-ends-in-a-loop/) to be causing the rewrite rule to go into an infinite redirect loop.

DNS is being managed by Godaddy (TotalDNS). Is there a way to configure DNS, or domain forwarding, so that I can accomplish the redirect prior to reaching the ISA firewall / IIS? This seems easier (if possible), than trying to track down and fix the ISA, IIS problem (though if someone has a solution for that, I'll take it).

If you are using IIS7 and you're using .Net 3.5 (at a minimum) the quickest way IMHO is to just quickly add this to your web.config file.

<system.webServer>
<rewrite>
<rules>
    <rule name="CanonicalHostNameRule1">
        <match url="(.*)" />
        <conditions>
            <add input="{HTTP_HOST}" pattern="^www\.example\.com$" negate="true" />
        </conditions>
        <action type="Redirect" url="http://www.example.com/{R:1}" />
    </rule>
</rules>

Note: in this example its from a non www url to a www url

Hope this helps buddy.

I retract my statement that the article above did not solve the problem. I just didn't try enough variations. In the ISA server policies, "To" tab, "This rule applies to this published website" textbox, I changed the field from www.mywebsite.com -- which is how it is listed in IIS) to just be MyWebsite... it appears that I could make this any text string, as long as it is not the name of the actual site as used in the redirect (both mysite.com & www.mysite.com caused the infinite loop). Changed it as described above and problem solved. Thanks for the nudge mcandre. – Gene 0 secs ago

If you are developing on ASP NET, then there is a simple fix that you can apply by using the application_beginrequest event of the global asax

Why do try complex things? Just try the below code with the filename .htacces and upload in the root folder of your website host server (public_html).

RewriteCond %{HTTP_HOST} ^www.example.com$ RewriteRule ^/?$ "http://example.com/" [R=301,L]
