[dancer-users] pass through route

I have too wide regexp in the route and it matches my javascript which is loaded from the main template the following way. <script type="text/javascript" src="<% request.uri_base %>/javascripts/imagesloaded.pkgd.min.js"></script> Can I create a pass through route which would filter out all /javascript matching ? I mean to filter in the sense that javascript will be parsed by the browser and not by dancer. Or may be I can achieve that with before hooks ? Thanks!
