This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
I would like to request a "paranoid mode" where NetBeans record log of all network activity to/from Internet (outside my local network, it may be customizable). This mode would have little/no use for normal users, but is required for auditing network access and also to debug platform problems related to network access.
You can already use -J-Dsun.net.www.protocol.http.HttpURLConnection.level=100 option to let Java log the network traffic. For "paranoids" it should be more reliable than a log specifically created by NetBeans. ;-)
