As Ray explained already, we don't offer any way to flush or reset the
connection pool today. What would your suggested approach be if you got to
wish for how it would work?

Currently I monitor the network interface change myself. So I know exactly when network has changed and when the whole connection cache becomes invalid. For time critical requests reusing connections will give a big performance gain, however having long timeouts after connectivity change makes it unusable. If I could wish I'd like to keep the multi interface and non time critical requests in flight and have the option to manually clean unused connections from the cache.
