# the following two options are unsafe and not always necessary:

sslproxy_cert_error allow all # It would also allow SSL connections which might be unsecure.
sslproxy_options ALL # Enable various bug workarounds suggested as harmless by OpenSSL.
sslproxy_flags DONT_VERIFY_PEER # Accept certificates that fail verification.
