How does your customer system handle this?

http://localhost:8080/aSite/aPage?query=I%fear%dead%results

badly, obviously :)

Possible solutions:
1) You can still try in servlet 'aPage' to grab the request using
request.getQueryString() which should returns you "query=hi%everybody"
2) You can write a servlet filter for /* which will create a new
HttpServletRequest Object with parameters you parse in your way from the
getQueryString() above
3) You can open tomcat source, patch the url decoder, and use it

What ever solution is choosen, customer will be bound to a side effect
of error handling in server.
