ROOT_URL and browser URL rewrite

I have set my ROOT_URL=http://localhost/myApp. When I open a web browser to http://localhost:3000/myApp, the page loads correctly, but the /myApp is trimmed off the URL shown in the browser. Navigating around the site, the URL changes appropriately, missing the /myApp prefix.

The issue I have with this is that saving off the URL to navigate to pages later is incorrect since it is missing the prefix. Is there a way to not have the prefix stripped? I see in the traffic going to the server that it does have /myApp in all the requests.
