Fixed.
Regarding (HttpClientContext.PROXY_AUTH_STATE + this) I also have doubts:
- minimal number of authstate, that we should store = Number of Requests in
Test Plan. (each request can use own proxy). Does the AuthState is Thread
Safe and we can share it between threads? I think no and it'll better to
store Number of Requests in Plan * Number of Threads AuthStates.
- Also in case if we use dynamic proxy we can not reuse saved AuthState:
