If you are running a big site with multiple servers, you do NOT want
to run
Apache in front of your Tomcats -
All that you do is increase latency, and half your performance. The HTTP
connector in TC 5.x is more than adequate to deal with heavy traffic
loads.
To be honest, I try not to use Apache at all any more, and tend
towards lighttpd
- depending of course on the requirements.
We deliver our images via a separate url ie: img.domain.com and
www.domain.com.
We have the images delivered via a lighttpd, and our dynamic content
delivered
via tomcat - we currently do our load balacing with an F5 BigIP for
these two
fully qualified host names. Yes - you can do all sorts of snazzy
things with
a proxy (like apache and mod_proxy/ mod_jk) out front - but I do not
think
it is worth the cost of the performance that is lost...
We did some tests 2 years ago for our system and discovered, with
Apache and TC
running on the same machine
With mod_jk, apache 2.0 and TC 5.0
50 requests/ sec
With just TC5.0
100 request/ sec
...
As for security - you have TC running in both cases - mod_jk passes
the requests
unfiltered straight through....
Therefore by adding Apache, you are only adding something else to go
wrong -
be broken - not solving any problems...

Hi Tim.
And all of you out there. There is one thing that keeps bothering
me. I AM a
configuration fanatic and when I build my own version of Apache
(Tru64 UNIX, in
case anyone is screaming "use RPM!"), I tend to build it loaded
with modules,
mod_jk1/2 included.
