I also emailed this question to the people that worked on this bug.
It's written hhere that redeploy was implemented as an undeploy followed by a deploy.
Why does Cargo not allow the user to choose what to do? The TomcatManager class allows the user to choose whether to use the 'update' request parameter, but the AbstractTomcatManagerDeployer always uses this class with update=false.
Do you see a reason to prevent the user from updating a previously deployed war?
Thanks for your time and consideration,
