Hello, thanks for your responses,
I initially thought use a proxy for load balancing but is not
applicable in the context described (a single instance of a service from a
third party). is actually a web application that that exposes part of its
functionality as a web service, the application is not in cluster.
Is possible that synapse capture the requests, placing them in queue
and if a specific request no answer after a specific time then cancel the
request and send an error message to the client for retry the request?
@Hiranya: "Synapse can however help reduce the load on the service with
techniques like caching and throttling". Can you give me an example or link
on this?
Thanks and regards,
