Run ASP.NET MVC website in sub directory (map route values)

Hi there,

I'm running a few websites under my Winhost account in different sub-directories, and use the Web.Config file to redirect different domain names to the sub-directories.

<rule name="Site" enabled="true" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" pattern="^(pines\.)?stevenmclintock\.com$" />
<add input="{PATH_INFO}" pattern="^/PinesVilla($|/)" negate="true" />
</conditions>
<action type="Rewrite" url="\PinesVilla\{R:0}" />
</rule>

Unfortunately, there is a problem with one of the websites (ASP.NET MVC) when submitting a form to a controller. E.g. http://pines.stevenmclintock.com/Login. What should be happening is the user should be logged in, or the model returns a validation error (e.g. http://www.pinesvilla.com).

What I can see so far is the POST request is returning a 301 redirect and then a GET request. The advice I've had so far is to change my route values, but I'm not sure what to try?

Would anyone know how to solve this?

Thanks,
Steven.
