releaseConnection

public void releaseConnection()

Description copied from interface: ConnectionReleaseTrigger

Releases the connection with the option of keep-alive. This is a "graceful" release and may cause IO operations for consuming the remainder of a response entity. Use abortConnection for a hard release. The connection may be reused as specified by the duration.

Specified by:

releaseConnection in interface ConnectionReleaseTrigger

abortConnection

public void abortConnection()

Description copied from interface: ConnectionReleaseTrigger

Releases the connection without the option of keep-alive. This is a "hard" release that implies a shutdown of the connection. Use ConnectionReleaseTrigger.releaseConnection() for a graceful release.

Specified by:
