Re: Loadbalancing question--Please help if you can

Hi Michael,

I unfortunately cannot spend time helping you with Tomcat 3.3, as I 
would have
to replicate your setup to try to fix the problem.  What I can tell you 
is that I have
successfully configured a load balanced tomcat 4.02 server and that 
requests are
being sent to both tomcat servers.  I have taken the time to describe in 
details how
I set up the system. The web page is at http://www.ubeans.com/tomcat.;  I 
hope that
this will be useful to you.

Regards,

Pascal Forget

Loadbalancing question--Please help if you can

[Michael Molloy]

This is the 2nd load balancing question I've asked of the group in the last 
week, and I haven't received a single response. I've looked on the web & in 
the archives, but can't find an answer. 

Is anyone actually using the load balancing in 3.3a? I'm sure that there are 
some. My company would like to use Tomcat for a lot of future work, but I've 
got to get the load balancing working before we can commit to it 100%. If 
someone has some insight into the problem I describe below, please let me 
know. Maybe it's as simple as I'm testing incorrectly, but if that's the 
case, someone please point me in the right direction.

Thanks
