Why WebdavSession close HttpConnection ?

Hi all,

On the client side of my application I try to have a pool of
HttpConnections to reduce to connection cost to the webdav server (I
use https).

Trying to use webdavclient lib, I found that WebdavSession was closing
the HttpConnection on its closeSession.
Is there a reason for that ? I think WebdavSession should release the
connection in the HttpConnectionManager. Am I right ?

Maybe I'm not on the good way...

Thanks for your help,

Guillaume
