I don't know if this is any type of solution, but I noticed in the mailing
archives that there might be a problem with mod_jk and ajp13? I'm going to
try removing the ajp13 'worker', just use the ajp12 'worker' tonight at
home and see if it helps.
Another thing that is really weird about my jsp problem is that if I don't
use the jsp:forward on this particular page, it only executes once. When I
add the jsp:forward back in, it executes twice. Go figure.
Keep me posted if you figure anything out and I'll do the same.

Please
respond to
Tomcat Users
List
So, by the lack of response, I can assume no one has figured out how to
solve this problem? I know there were a few others who had dealt with
this problem, but no solution... I hope someone can here can try and help
out with this.
Thanks to anyone who responds...
