Hi Bhattman,
Yes i we have tested going direct from onlines to workflows which worked as expected... in our tests we were attempting to see if there was an impact on the application by routing the traffic via the LTM is this way. Effectively we would achieve the same thing by going direct however there are benefits for using a workflow pool which could be more beneficial in the long run (such as we would be able to add/remove members to the pool for maintainance without having to stop the application or scale up the number of workflow members should there be a issue with load in production).
Thanks for the assistance all!
