Given that it’s been out for a while I thought I should spring for the latest Apache httpd, version 2.2.0 I really like the cleanups that the httpd team has done with the configuration files, the modules, etc. I usually set bigger web servers up with separate include files for virtual hosts, especially if there is change control on the files. That way I can build a process for people to muck with the virtual hosts and leave the main server settings alone (and secure). I also appreciate the level of default security the server has.
I don’t really tax Apache much anymore. A long time ago I had a few web servers that ran on underpowered hardware, but nowadays something like a Slashdotting can be handled by a a 2.4 GHz Pentium 4, at least for a mostly static site.
