从IIS或ASP.net MVC或haproxy中的URL删除子域

Question

Is it possible to remove a subdomain (or basically treat it like www) from the URL?

Example: subdomain.domain.com/specific/link/forsubdomain -> domain.com/specific/link/forsubdomain

and not have it point to the primary domain and return a 404 error, example: domain.com/specific/link/forsubdomain -> return a 404 because it only exists in the subdomain.

If it's possible to do something in Haproxy as well Or disguising URLs in ASP.net MVC Route table modifications im open to it.

Not just IIS configuration.

Just wanted to know if it's possible to change the URL as i described and still have it point to the subdomain site.

If I understand your question correctly you are refering to canonical URLs.

Within IIS you can use URL Rewrite , which is a module you can install manually or via the Web Platform Installer (if it's not already installed).

This allows you to create a url rewrite rule which you can configure per site, something along the lines of;

<rule name=”Redirect URL to WWW version”
    stopProcessing=”true”>
<match url=”.*” />
<conditions>
    <add input=”{HTTP_HOST}” pattern=”^example.com$” />
</conditions>
<action type=”Redirect” url=”http://www.example.com/{R:0}”
    redirectType=”Permanent” />
</rule>

You can add the rules manually to the site's web.config file or use a GUI within the IIS site manager tool.

There's a lot of reference and a number of tutorials available from Microsoft and numerous bloggers.

An example of a complete web.config just doing this type of redirect.

<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="WWW Redirect" stopProcessing="true">
                <match url=".*" />
                <conditions>
                    <add input="{HTTP_HOST}" pattern="^contoso.com$" />
                </conditions>
                <action type="Redirect" url="http://www.contoso.com/{R:0}" redirectType="Permanent" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
