Happy New Year to all.

Thanks for reminding me about this, it seems to have fallen off my TODO list
somehow.

It seems that the existing behaviour was designed more with proxies in mind
rather than using an alternate server for checks. Personally I think proxy
support would be better handled in other ways so I have changed the
behaviour to what you expected - what I would have expected to. Obviously
whoever origonally wrote the code (not me) had different ideas. In any case
the patch below, which will appear in CVS shortly, should resolve your
problem.
