I have multiple Drupal 5.6 sites running well under ISPConfig2 using this. I want to make sure there are no known issues if I follow this. Why? The ONLY reason I want to do this is so that I can try mod_gnutls to see if I can get Multisite SSL on a single IP working ... since it appears to be very promising using this. References: 1) Server Name Indication 2) SSL-enabled Name-based Apache Virtual Hosts with mod_gnutls 3) name-based virtual hosting with ssl 4) I don't want to have to do this (patching, recompiling, etc): How To Enable Multiple HTTPS Sites For One IP On Debian Etch Using TLS Extensions Thanks in advance for any thoughts, feedback, or suggestions. Sorry for any overkill, but I just want to make sure.
