Debug variables, view as URL - how to?

I often debug some JSP portals and have variables that contains a url as a String (i.e. "localhost:8080/path?p1=v1&p2=v2"). Since url params cen be long, its not always easy to see what u are looking for. Is it possible to write URL parser for debug variables, so I can show url not a big line, but splitted by parameters?
