Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
15.0.0, 15.0.1,,,,, 15.1.0,,,,,, 15.1.1, 15.1.2,, 15.1.3,, 16.0.0,, 16.0.1,

Fixed In:

Opened: Mar 19, 2020

Severity: 3-Major


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'.



Fix Information

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.
