asp.net client routing with page.js

I am trying to build a simple asp.net application (webforms) and I would like to do the routing in the client. This is a SPA.

I am using the page.js library to handle the routing. My development environment is visual studio 2015 Enterprise. This is an example of a routing

page('/admin', display_admin);
page('/items/:sub/:id', display_item);

In the server-side, I setup things so that for every url request, index.html is loaded (since routing is handled in the client) and the appropriate route handler is called and executed. In the web.config I have:

<configuration>
<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" />
  <rewrite>
    <rules>
      <!--Redirect selected traffic to index -->
      <rule name="Index Rule" stopProcessing="true">
        <match url=".*" />
        <conditions logicalGrouping="MatchAll">
          <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
          <add input="{REQUEST_URI}" matchType="Pattern" pattern="^/api/" negate="true" />
        </conditions>
        <action type="Rewrite" url="/index.html" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>
</configuration>

see this article ASP.NET 5 and AngularJS Part 3, Adding Client Routing

Everything works fine when the custom url is of this form '/xxx' for example '/admin' , '/items' etc... But it does not work for complex url where the path of the form '/xxx/yyy/zzz'. ex: 'items/cars/10'. In visual studio during debug the application craches:

enter image description here

You can see that the server (embedded webserver in visual studio) tries to load resources for page "1" from the folder at 'localhost:port/items/c/' which of course does not exist. This request does not reach my server where a redirect would occur to page 'index.html'.

How can I implement client-side routing in asp.net (with .html files, not .aspx files) and with complex url path?

I am guessing that this is problem related to the embedded webserver in visual studio (which is a light iis version...)

Any help, any hint would be greatly appreciated

Thank you stackoverflow community

You are most likely using relative paths to scripts. This means the browser will assume the page being served is under /something/else/entirely and will ask for it there. Use an absolute path as /bootstrap.min.js to make sure it's requested properly.

The server may internally redirect to /index.html with your configuration but the browser doesn't know that.

The reason why single level /something works is due to browser still assuming everything is on the root level. An additional slash and the context moves down one "folder."
