there are two answers, one easy and one difficult
Easy answer: mod_proxy, you'll be up and running in five minutes,
Hard answer: try upgrading jk, or downgrade, play around with the
configs, and spend the next few days fiddling :)
here is a great article on proxying capabilities with apache

Fairly regularly I have a page resquest visible on the 'Server Status' of
the Tomcat Manager that never ends. I have tomcat set to timeout sockets
after 120 seconds, and have mod_jk set to do the same. It always stalls at
4192K sent (is this a magic number?). I tried increasing the output buffer
size and have set JKOptions +FlushPackets on the off chance that it would
make a difference but it does not seem to. The stack trace obtained through
jconsole is below. Can anyone shed any light on this? Could my application
be causing this problem? This page has been running for 10209703ms at the
moment and while restarting Apache will cause it to exit, I am getting
really tired of restarting apache all the time to resolve these issues.
Anyone, anyone... Bueller, Bueller?
Thank,
Justin
