[imp] Problem with Domain Auto Detection

[geno@onshore.net]

Does anyone have any suggestions?  I can't be the only person trying to use auto
detection functionality for multiple domains virtually hosted on one server with
the same IP for all.  Can someone please break down how the auto detection
procedure works?
