ASP.Net Redirect Request from a specific URL to a particular part of my website

Question

Our Server Admin has setup a "Site Binding" in IIS for a website on the server, so that when an end user uses a specific url, it redirects to our site.

I need to be able to determine when one of these redirects has taken place, and then land the end user on a specific page on the website.

Can anyone help?

Answer 1

Your question says that users are getting redirected to your site, but that's not really how IIS site bindings work. They are more like aliases for a single site. If that is the case, and the site has multiple bindings and you want to redirect based on which binding was used, then yes you would use a rewrite rule in web.config system.webServer section, like so:

    <rewrite>
        <rules>
            <clear />
            <rule name="redirect" stopProcessing="true">
                <match url="(.*)" />
                <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                    <add input="{SERVER_NAME}" pattern="www.binding1.com" />
                </conditions>
                <action type="Redirect" url="http://www.binding2.com/pages/binding1home" />
            </rule>
        </rules>
    </rewrite>

Answer 2

You can find the binding name in Request.ServerVariables under: "HTTP_HOST" or "SERVER_NAME". If you have access to the server variables? If so you could than redirect to a specific page if the specified binding name is found. (see: MSDN)

Answer 3

Depending on how the redirect is setup you could try and use the UrlReferrer property of the current request:

Request.UrlReferrer
