Suppose now have HTTP proxy IP: 192.168.1.1 port is 80
SOCK5 proxy IP: 192.168.1.2 instead port is 80, but there are SOCK5 account password authentication account: user password: passd

How can you tell me the next in the MFC to the two IP proxy authentication is valid? Attach my own part of the code, moved from the Internet and tested under
Proxy IP address port password whatever written for don't know where the problem is effective for help!!

CInternetSession: : CInternetSession construct is called InternetOpen,
So try fill out the agent in the constructor parameters
