HTTPS redirects to HTTP for monitoring

[Andy Brezinsky]

We use Fortinet firewalls and SSL (HTTPS, FTPS, IMAPS, POP3S, SMTPS, 
SSH) inspection is a standard feature.  It works by rolling out a custom 
CA certificate from the device to all of the desktops and whenever you 
hit a SSL site, a cert signed with the CA is generated and presented to 
the user. If you look at the cert your browser has, you can tell the CA 
is different but most users aren't looking at that.

Our user base uses a lot of services that can't be forced to downgrade 
to HTTP so it's the only option.  Fortinet has some configurations that 
allow you to exclude certain sites from the MiTM 'attack'.  For example 
we don't scan banking, health care and personal privacy categories.
