Many moons ago I worked on a
servlet intensive project using JRun. After a lot of frustration we discovered that the JRun servlet session stuff had some serious problems and we had to handle sessions manually.
Later, I found out that the new JRun stuff had not fixed the problem. Then, talking to some engineers using other
J2EE servers, discovered that this is a very common problem.
Now I'm about to get hip deep in a new project that will require sessions. Should I roll my own or should I trust the built in stuff?
