A list of NTLM/NTLMv2 authenticating HTTP proxies.
Parent proxy, which requires authentication. The same as proxy on the command-line, can be used more than once to specify unlimited
number of proxies. Should one proxy fail, cntlm automatically moves on to the next one. The connect request fails only if the whole
list of proxies is scanned and (for each request) and found to be invalid. Command-line takes precedence over the configuration file.
