[support] Testing custom maintenance page without putting the site off-line (D6)

[Ken Robinson]

Is there any way to test a D6 custom maintenance page without putting 
the site into maintenance mode?

I've been tasked with creating custom maintenance pages on a D6 site 
that is in production and has no development/test server (I know -- 
bad design, but I wasn't in on the initial design). So now I have to 
test these without putting the site into maintenacne mode.

Thanks in advance,

Ken
