Severity: 4-Minor


Online documentation describes a persistence mechanism which uses the HTTP Host: header. However, this mechanism is not implemented, and attempts to use it generates an error.


Although this does not impact any existing functionality, the documented function is not available.


Online help for ltm persistence says that Host persistence can be enabled via iRule, but attempting to do so generates an error 'invalid argument host'.


There is no workaround at this time.

Fix Information

LTM Host: header persistence is implemented.
