I'm having trouble understanding why, when in my Durandal app, after I go to a detail page then back to a list I get a url with the detail page's url embedded in the current URL. 

For example:

When I start out I've got: `http://localhost:51429/#/`

Then I go to the detail page: `http://localhost:51429/physDetail`

Then I go back to the list page: `http://localhost:51429/physDetail#/physList`

Why am I getting 'physDetail#' embedded in the url? The problem is that if I hit F5 to refresh the html I get a 404.

I'm setting routes like this:

```
  var routes = [{
    url: 'physList',
    moduleId: 'viewmodels/physList',
    name: 'Physicians',
    visible: true
  }, {
    url: 'physDetail',
    moduleId: 'viewmodels/physDetail',
    name: 'View Physician Detail',
    visible: false
  }, {
    url: 'incentives',
    moduleId: 'viewmodels/incentiveList',
    name: 'Incentives',
    visible: true
  }, {
    url: 'membershipList',
    moduleId: 'viewmodels/membershipList',
    name: 'Membership',
    visible: true
  }];

```

Switching to the detail page occurs by clicking on a row in the list. 
The list HTML looks like this:

```
 <tbody data-bind="foreach: $root.physicians, delegatedHandler: 'click'">
    <tr data-click="physClicked">
    <td data-bind="text: contact_LastName"></td>
    <td data-bind="text: contact_FirstName"></td>
    <td data-bind="foreach: contact_Phones">
        <span data-bind="phoneFormat: fullPhone"></span>
    </td>
    <td data-bind="foreach: contact_Emails">
        <span data-bind="emailFormat: address"></span>
    </td>
    </tr>
 </tbody>

```

The js handler looks like this:

```
function physClicked(phys, event) {
  router.navigateTo("physDetail");
  return;
}

```

Return to the list (or another page) by clicking on a button at the top of the page. The button HTML looks like this:

```
<div class="btn-group" data-bind="foreach: router.visibleRoutes">
  <a data-bind="css: { active: isActive }, attr: { href: hash }, text: name" 
     class="btn btn-info" href="#"></a>
</div>

```

Should I be dis-allowing a jump to another page? Should I only allow a back button or doing a router.navigateBack() after a save or cancel?

I've tried to find some guidance on this at the Durandaljs site but either it doesn't exist or I don't know the right question to ask.

Thanks for any insight.
