Someone else just asked me this last week, so I wrote one (see
attachment). It's tested with C2.03. You'll need to compile this and put
it an jar and put that in WEB-INF/lib (let me know if you need more help
on this).
It is of course possible that there are multiple request parameter names
that match, but this matcher will take the first one that it encounters.
