Could any one please provide me some info regarding the "If standing in" assertion coming under VS Image Response step, and "If failover" assertion coming under HTTP/S Live Invocation step?
Any document related to that would be helpful.
These two assertions work to modify the virtual service model behavior as per the execution mode in which the virtual service is executing.
This should be helpful
I am unfortunately not able to access this doc.(i am getting 403-Forbidden Error).
Here is the 8.4 equivalent documentation: VSE Console Request Events Details Tab - DevTest Solutions - 8.4 - CA Technologies Documentation . Hopefully, that link works better for you.
Stand In mode first routes a request to the virtual service (the same as Most Efficient mode). However, if the virtual service does not have a response, the request is then automatically routed to the live system. You can only enable Stand In mode for a virtual service with a Live Invocation step. Stand In mode does not do any special tracking. It simply allows for a virtual service to fall back on the live service.
Failover mode first routes a request to the live system (the same as Live System mode). However, if the live system does not have a response, the request is then automatically routed to the virtual service. This mode is the opposite of Stand In mode. You can only enable Failover mode for a virtual service with a Live Invocation step. Failover mode uses the service image to determine a response if the Live Invocation step actually fails (as might happen if the live system were not available).
