Is this intended as a joke, Mandy :-)?

First: the final 6 lines should read "return xmlhttpcheck;" for the sake
of conciseness w/o loss of readability.

Second, this duplicates the code from Ajax.getTransport().  I mean,
scary duplicates, because it doesn't even use Try.These.  Of course,
maybe you're going for no-Prototype-dependency, but isn't this a
Prototype/s.a.u. list?

Therefore, the previous solution: !!Ajax.getTransport(), is way better,
wouldn't you say?

Best,
