Rails - May 2006 - Rails, SSL, and Web Server

I''m working on setting up the server that will host a Rails app for my
organization, and part of that app requires SSL(https) - some
controllers need ssl and some do not.  My question is if there are
others out there that require the same, and if so, which kind of
server setup (lighttpd, apache, etc) are you using?

Thanks,
Josh
