Allen, thanks for pointing me at mod_jk. It works better than proxy or
rewrite!
I've implemented it here now on Apache 2.0 (under WinXP) connected to Tomcat
4.1.24 (Solaris).
with mod_jk 1.2.5. Works great! In case it helps, I'll attach my config
files:
Tomcat's server.xml:
---------------------
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
port="8113" minProcessors="5" maxProcessors="75"
acceptCount="10" debug="20"/>
workers.properties:
-------------------
# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=192.168.1.62
worker.worker1.port=8113
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300
Apache httpd.conf:
------------------

Hi.
Can you post the relevant parts of your httpd.conf file? Also, I missed
this in the thread if it was mentioned, but what version of Apache are
you working with? I ask, because it looks like from my setup that
Apache ditched the AddModule directive in Apache 2.0.xx.
LoadModule needs to be in your httpd.conf file before the AddModule
directive under Apache 1.3.x as in:
# All the other LoadModule directive here.....
LoadModule jk_module modules/mod_jk.so
# Further down, all the AddModule directives here....
AddModule mod_jk.c
It'd be helpful to see the JkWorkersFile directive, JkMount directive,
and the contents of the jk workers file.
--David
Just tack it on to the end of the list of LoadModule directives. Then
use AddModule at the end of the list of AddModule directives.
