在Google Appengine中的版本/后端之间共享会话

Question

I have a fairly big application hosted on appengine. It has various components and each component is done by a different group in the company.

I am looking to break down the application into various submodules each hosted separately as a version. eg: module1.mainapp.com.

Since Google uses a db for sharing sessions and the db is shared among the versions and backends, is there a way to share sessions? Currently, it looks like each session is different.

I understand that we can put <SessionCookie domain="example.com"/> in web.xml in normal applications but I am not sure if AppEngine honors this.

Thanks.

This isn't possible, because cookies are set by the user system, and the cookies are per domain.

In any case, I wouldn't recommend this approach - modifying your URL scheme to suit your app's internal organization is a nasty hack; the URL scheme you present to your users needn't have any direct relationship with how you handle requests.
