I set my MT installation up to use SSL. While I was at it I also made it run under mod_perl again. Since I moved to an Apache 2.x based installation I've used it as a CGI (yuck).
I was running mod_perl 2.0 on the MovableType server anyway as I use it for authentication for the DAV server (so I can use my MT login to access the files). Now I made mt.cgi run under ModPerl::Registry on mod_perl 2.0. This is a test post to see if that still works. :-)
Update: Yup, works fine. Awesome.
