Thanks für your answer.
I will try to make 'my conclusions'.
Since I am using the SimpleHttpConnectionManager that is not thread safe
(in a multi thread environment as a servlet container as tomcat is) I
correctly do use the instance of the simple http-connection manager only as a
local
variable that will be garbage collected after my http request has been made.
But, to release ALL used internal resources it is not sufficient to allocate
the instance
of the simple http-connection manager just locally, I also do need to use
#closeIdleConnection (after a #releaseConnection) to free these network
resources as well. (I checked this also looking into the code of the
simple http-connection manager.)
Correct?
Regards
Armin
