JCR session handling

[John Tranier]

Hi everybody,

I would like to have advices about how I should handle JCR sessions in 
my application context.
I have read the guide on the wiki, but I'm not clear about what is 
called "transient mods", if my application fall into it, and finally how 
to deal with that case.

I am using a Jackrabbit repository to handle personal storage space for 
users of my web application. I've defined personalized access for each 
users, so it's about personalized accounts.

Up to now, I've handled sessions by creating a session for each http 
request. But since my application makes use of AJAX to display the tree 
view of the personal space of a user, a lot of requests may be launched 
in sequence, causing a lot of login/logout...

Would it be a better practice to use a http session scope instead of 
request scope, with eventually a TTL after which a session would be closed?

Thanks in advance,
John
