Recently I've seen strange behaviour with services from different applications being mapped to an application although the applications and services are totally independent. Further investigation of the waterfall instance for a user revealed that although there were just 2 XHR resources triggered for this XHR action. but 4 PurePaths are available for analysis. Two of them for the application itself (that is correct) and two of them pointing to another unrelated application.
I'm not sure what is happening here but I think the PurePaths pointing to another service have been triggered by a different browser window of the same user.
Maybe someone could reveal in detail how the PurePaths are assigned to waterfall resources?
Solved! Go to Solution.
However, in this case, I see more PurePaths in a user action than the number of actual requests and it's not the case of HTTP redirects. If there are HTTP redirects involved, from RUM you see only the single resource request, but multiple requests on server side might have been invoked. This is then visible as the redirect time for a resource.
