When an HTTP request contains the 'Connection: close' header, the BIG-IP system shuts the TCP connection down. If a virtual server has a OneConnect profile configured, the BIG-IP system fails to close the connection for HEAD requests disregarding a client's demand.
Connection remains idle until it expires normally, consuming network resources.
-- A virtual server has HTTP and OneConnect profiles. -- An HTTP request has the method HEAD and the header 'Connection: close'.
When an HTTP HEAD request contains 'Connection: close' header and a OneConnect profile is configured on a virtual server, the BIG-IP system shuts a connection down after a response is served.
