simply, host headers and ssl don't work together! :>

the host header information that iis uses to direct you to the right site
is encrypted as part of the ssl process.  this means that when you try
and access https://rep.thermon.com iis doesn't know where to direct you,
so you end up at the first site that can handle ssl with any ip address -

if you want to use ssl you need to have a unique ip address for each site
you want to access.  alternatively, there are ssl off-loaders that do all
the encryption/decryption for you, so iis sees the host header
information and can direct you appropriately.
