Just an FYI that I'm going to be upgrading apache tonight on the ufies box. There are some configuration changes between the old and new verison, so it might be a bit bumpy. I'll test out everyone's sites before I declare it properly installed though. Just in case any of the 18 people who read this site notice it down :)
Update - All went well, things all seem to be working, let me know at arcterex awt ufies dawt org if anything is busted. Also, please make sure your php and perl apps/cgis don't blindly execute code, k? :)
