we have Spark 2.5.8 with Proxy Support by mean of a patch (http://www.igniterealtime.org/issues/browse/SMACK-226), as i wrote in previous thread http://www.igniterealtime.org/community/message/179627
That patch adds SOCKS and HTTP proxy support.
HTTP proxy with Basic authentication, but nothing about NTLM, Kerberos or Negotiate Proxy authentication.
We are working on it.
Some idea on how to carry out?
thanks in advance
