Very true, otherwise you need to run Tomcat as root. Also, Apache itself has some nice features, like mod_rewrite that can be helpful to handles changes in structure and such. I guess these days we also need to know if we're talking about the 3.2 or 4.0 versions of Tomcat since there are things like HTTP 1.1 in Tomcat 4.0. I'm still in 3.2 land and investigating whether 3.3 or 4.0 will work better for me in the future. The "fear" is that 4.0 is not as well tested yet. I also recall that there was (is?) a problem if lots of concurrent requests came in and Tomcat had to service them all using threads, whereas Apache will stop at a maximum rather than continue to try to service. DoS attacks are nasty no matter what, though. Also, if you use tools like WebTrends and such, they all know how to work off of Apache log files, so that format of log message can be quite important to analyze a site's usage, errors and performance. And can you roll log files with Tomcat yet? With Apache you can roll your log files so that they don't just keep getting bigger. David
