Access proxy from Client

[johnsmith1232541]

I have an app where I'm spawning futures that take a Client as an argument and perform multiple operations and then returns the Client back.
Each client is using a different proxy and upon return of the future, I'd like to know which proxy it was used, however the attributes are private. How would I go about this?

As a side note, I'm building new clients for every connection as each conn needs a new proxy. Is there a cheaper way to do this, by changing proxies without having to build a new client?

Thanks
