Secure mod_perl - i.e. mod_perl in an Apache that's shared with other web sites mod_perl in any language supported by Linux Interactive debugging of your perl on live requests inside a live Apache See http://user-mode-linux.sourceforge.net/slides/wvu2002/wvu2002.htm The section that's relevant here starts at http://user-mode-linux.sourceforge.net/slides/wvu2002/img9.htm There are also some wackier possibilities which I'm not sure are terribly useful or practical, but would still be interesting to look at, such as: Treating HTTP requests as processes, so # ps uax ... apache 1120 0.0 0.6 4388 1536 ? S 13:46 0:00 GET / HTTP/1.0 ... # kill -9 1120 or # nice -20 1120 Treating HTTP requests as packets and using Netfilter to manipulate them. Jeff
