Hi, A few months ago, I submitted bpo-35153 with a PR to allow to set headers from xmlrpc.client.ServerProxy. Is there a core developer willing to review it? It will be great to have it for Python 3.8. https://bugs.python.org/issue35153 https://github.com/python/cpython/pull/10308 Thanks, -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.krier@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
