I have a main website app written in ASP.NET’s MVC 3. Now, what I would like to do on occasion, is add a subdirectory, mark it as an application and run a whole different MVC 3 app from that directory. For instance, my site is at http://sol3.net. I am working on a small MVC app for a client and I’d like to publish it on my site so he can take a look at the progress, offer feedback, etc. So, their site would be at http://sol3.net/projectA. Having done this with a test app all I am getting is a 500 error.

Are there any best practices on how to set this up?

And yes, I already know about web.config inheritance problems. Fortunately my web.configs are not too large and I think I have most everything handled there.

NOTE: What I am trying to do is temporarily run a MVC app (App B) from within an app folder on an already active site (App A). App A and App B do not share anything in common and App B will eventually be moved to its own hosting site.

NOTE #2: The Answer…

I believe it is IIS7 and higher that allows you to add a redirection in your root web.config. Here is what I ended up doing instead of doing it via IIS Manager:

<system.webServer>
  <validation validateIntegratedModeConfiguration="false" />
  <modules runAllManagedModulesForAllRequests="true" />
  <rewrite>
    <rules>
      <rule name="APP 1 - Sub domain to sub folder" enabled="true">
        <match url="(.*)" ignoreCase="true" />
        <conditions logicalGrouping="MatchAll">
          <add input="{HTTP_HOST}" pattern="^(www\.)?app1\.sol3\.net$" ignoreCase="true" />
        </conditions>
        <action type="Rewrite" url="app1/{R:1}" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

    You would add a subdomain via an alias in your DNS records. Some registrars will let you do this yourself, but some sell this as a feature. A whois on your domain says it’s registered with GoDaddy. Check this out. http://help.godaddy.com/article/4652#addsubdomain1

    Edit – OrcsWeb allows for remote management of your web site via IIS 7 Manager. This should allow you to edit the host header. http://www.orcsweb.com/blog/brad/iis-7-manager-for-remote-administration-installing-and-connecting-to-a-site/
