How to pass URL parameters to vnc_lite.html?

[gkprabhakar]

vnc_lite.html states:

Connect parameters are provided in query string:
    http://example.com/?host=HOST&port=PORT&scale=true

How should I pass query strings to vnc_lite.html in this integration?

I've tried modifying __init__.py to contain:
'mappath': {'/': '/vnc_lite.html?scale=false'},
instead of
'mappath': {'/': '/vnc_lite.html'},

However, this does not have any effect.
