Using Query String Parameters while trying to navigate to a page on app compartment from web compartment

Question

There is a need in my app for the web compartment to navigate to a page that resides on the app. Right now, I am doing it like this:

    window.location.replace("ms-appx://<pageurl>");

To be able to do so, I had to explicitly allow this page to be navigable from outside by doing:

MSApp.addPublicLocalApplicationUri("ms-appx://<pageurl>");

I would like to use query string parameters when I do window.location.replace, like this:

    window.location.replace("ms-appx://<pageurl>/?q=what");

In turn, this caused me to do a wildcard match in MSAPp.addPublicLocalApplicationURI like this:

MSApp.addPublicLocalApplicationUri("ms-appx://<pageurl>/*");

For some reason, the app is unable to resolve this uri. Is there some other way to use query string parameters, or is it something that is just not allowed?
