There are also fewer things to fail, and a smaller learning curve for your system administrators (if they don't already know Apache httpd and the JK connector). > I think apache as a front end is a more flexible and secure solution. > -> if apache fails, tomcat is not affected ... but is inaccessible.

There have been a couple of benchmarks on this, most recently by Peter Lin (available at http://tomcat.apache.org/articles/benchmark_summary.pdf). They showed that Tomcat 5.0 and higher are sufficiently efficient at serving static content that you'll saturate your network before you run out of resources on the server. Peter saturated a 100Mbit/s LAN connection. > Am i wrong ? As i have currently nothing pre-installed on it... and > it would be fine to know what you are thinking about it.

I like systems with fewer moving parts - they're generally simpler to manage, more robust and easier to debug when they go wrong. And security-wise, I'd much rather put a proper firewall in front of a web server than rely on httpd to catch all the possible attacks! You may have other reasons to add httpd. Unless you have very slow boxes and very fast network connections, speed of serving static content is not a valid reason. I'd never assume httpd is any more secure than Tomcat, so security (to me) is not a valid reason. You may want to put httpd in front, simply so that you can load-balance and scale Tomcats as your application grows - that's a valid reason if you don't want to use a hardware load-balancer, and plenty of folks load-balance that way, including some quite large sites with quite demanding SLAs. Just make sure you know what you're gaining by adding the extra system! - Peter --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
