defining external http viewer for GNUS

[Rainer M. Krug]

Hi

I would like to use an external viewer (conqueror) to view html emails from 
time to
time, but I would not like to change my emacs default viewer (x-www-browser). 
Is there a
way of defining one (conqueror in my case) only for gnus?

Thanks,

Rainer

PS: the more I use gnus (my fourth day now), the more I like it
