Working for a very big customer, I found a very nasty interaction between Sun HttpClient (JDK 1.4) and Http Load Balancers.

The bad behavior of Sun HttpClient is well known: some guys suggested me to use the Axis Web Client. Anyway you can solve the issue adding these three parameters to the JVM launch line

Some times ago I have the lucky to read "Producing Open Source Software":
[...] a book about the human side of open source development. It describes how successful projects operate, the expectations of users and developers, and the culture of free software.

I am not a big fan of portal software, because it is not cheap to delivery.
Portal specification is heavy to use and implement, and can have a reason only in very big corporate company.
