I think it's the unescaped ampersand rather than the ID per se.
I'm not sure whether the recommend fix is to escape the ampersand,
as in "/cgi-bin/cone/cone_wrapper.cgi?TODO=2410&amp;ID*=*201005MHGZuL"
or to represent it using % notation.  I am sure that someone more
expert (or more awake) than I will advise, but try the former
in the meantime.
