namloan updated HTTPCLIENT-2350:
--------------------------------
Description:
In Bisq2 [1] we are querying .onion endpoints through HTTP to retrieve some
data. To do this, it's needed to connect through a SOCKS proxy and let it
resolve the hostname through the Tor network as a public DNS resolution will
fail. In HTTP client 4.x we had it implemented as explained in [2]- using a
FakeDNSResolver and custom socket factories that do not try to resolve the
.onion hostname to an InetAddress.
We've just migrated to HttpClient 5.4.1. Finding out how to do this required
extensive hours of debugging the library, in particular for preventing the
public DNS resolution as custom socket factories are deprecated. Find our
solution in [3]. In essence, we created our own
PoolingTorHttpClientConnectionManager to be able to inject our own
HttpClientConnectionOperator that doesn't attempt to resolve the .onion
hostname to an InetAddress [4]
Is there a simpler way to this? If not, it would be great to count on a simpler
option so that we can remove our own connection manager and connection operator
given that they are mostly duplicated code from the library.
