If we had a “referrer” that kept track of the previous service that was executed this would go into the service provider logs. We could then set up a service (pull) that Moby Central could use to gather this information from the logs. Alternately, we could “push” from the service as it is executed…
For us as client writers the first step is to ensure that we add the “referer” header… so we gotta do that! Probably the LSID of the previous service?
All in all, this will give us the ability to make the ‘next most popular choice’ very visible in our clients – filtering out the lesser-used services and bringing the cream to the top.
