ASP MVC routing works differently in a subdomain

Question

I have an application hosted on an Amazon server with two instances, one for test and one for production.

ie.
On server 123.456.789.123 the app instances are
- wwwroot/myappuat
- wwwroot/myappprod

So the subdomain myapp.mydomain.com DNS settings point to the server 123.456.789.123
And rewrite rules have been set for these instances, let's just look at production

<rule name="myapp.mydomain.com" stopProcessing="true">
<match url=".*" />
<conditions>
    <add input="{HTTP_HOST}" pattern="^myapp.mydomain.com$" />
</conditions>
<action type="Rewrite" url="\myappprod\{R:0}" />
</rule>

The trouble is when RedirectToAction seems to behave differently than when I was just testing on localhost in development.

For instance:

RedirectToAction("Login", "Home")

will redirect to http://myapp.mydomain.com/myappprod/Home/Login instead of the intended http://myapp.mydomain.com/Home/Login

I suspect I need to modify the routing settings in RegisterRoutes. But I don't know what to do.

Any help on this will be greatly appreciated.

Answer 1

I found where I went wrong.

Tilda's.

For example there is a redirect from the URL authorization to the login page which was set like this:

<authentication mode="Forms">
  <forms loginUrl="~/Home/Login" timeout="2880" />
</authentication>

Since the URL has been rewritten, the path still included /myappprod. Removing the tilda fixed it

<authentication mode="Forms">
  <forms loginUrl="/Home/Login" timeout="2880" />
</authentication>

One extra thing while I'm on here. Make sure you use Url.Content("~/url/here") not just "~/url/here". Particularly with those tildas.
