LB::reselect - LB_SELECTED event occures twice

Hi,

 

 

Here's some info you might find useful.

 

 

1) ASM virtuals work a bit differently than non-ASM virtuals, in that, as you've observed, the LB_SELECTED rule event does fire twice. The first LB_SELECTED indicates which server the request will eventually be serviced by - the second LB_SELECTED is due to the request being routed to ASM for processing.

 

 

ASM virtuals use httpclasses, so the appropriate place to select an alternate destination for a given request is in the HTTP_CLASS_SELECTED rule event, which fires between HTTP_REQUEST and LB_SELECTED.

 

 

Your iRule should work if you move the code in LB_SELECTED to HTTP_CLASS_SELECTED, provided you intend for the request to go through ASM.

 

 

2) Currently, BIG-IP log files are rotated daily and one week's worth of log files are kept on the system.
