Hmm, that's a good question. I assumed the answer would be "use
java.net.URL" but there's no way to parse the query string. You can use
getQuery() to get the whole thing, which seems a bit safer than your
method.
You can look at this code. It has a trace option at the top. I set it to
true. It will do what you want but I am not happy with it. I think I can
clean it up and make it tighter. Anyway, here ya go. This may get you
started in the right direction.
Here is test output with trace of the data you submitted in you message:
passing.
