Question

I’m using Google App Engine and a servlet-based application.

I know that the container specification says that when called response.getSession() by a servlet the whole session management process starts in the background and the response should contain a sessionid cookie. The problem is that I’m not getting the that cookie and the problem comes from the server because I’ve tried sending a “hand-made” cookie and that one is received correctly.

Answer 1

It looks like sessions are disabled by default so you have to enable the feature yourself by adding <sessions-enabled>true</sessions-enabled> to the appengine-web.xml file.
