I have a problem with tomcat - apache and I was hoping anyone could help me.
I have an apache server with ssl installed on the machine. On another
machine I have tomcat installed. Now I need to have the apache server
forward all *.jsp request to the tomcat machine so that tomcat can do it´s
job and then return the result to the apache server. I am using ajp13 to
forward the request to tomcat. I have configured my servers according to the
steps below but it doesn´t work properly. Sometimes the match doesnt add up
at all and the wrong file is returned and most of the time the session is
dropped for some reason. If I do request.getSession(true) then
session.isNew() is always true.
Anyone knows what to do?
