A proxy server built with c# can be both normal and MITM Proxy

C# Proxy Server

This is an open source proxy server for windows machines with .NET Framework installed.
The server can act as a normal proxy server, forwarding all traffic to the destination without any tampering.
But the server can also act as a MITM Proxy Server, intercepting, modifying traffic automatically, or based on patterns.
This program is a console like program.

Using it as Normal:

Type set ip any and press enter, to set the IP of the server to any, open out to the internet.
Then type set port 8080 to set the port of the server to 8080 (most proxy servers use port 8080).
Then type start to start the server, accept any firewall warnings, the server will not work without accepting the firewall pop-up.
That's it, your server is now working normally, to save the current settings type:
save normal - This will create a normal.xml file under the profiles folder.
Any time you close the program and re-open it just type:
load normal - this wil load the previously saved settings.
Loading a settings file will NOT start the server, you need to start it by using the start command
For advanced settings read: Advanced Settings
For MITM stuff read: MITM Mode
Features planned to be added:

• Capture HTTP Basic Auth Requests
• SOCKS5 Mode
• Communication with the C# R.A.T Client

c-sharp-proxy-server's Issues

Suggestion to support IPV6

In some circumstances accessing IPV6 the exception "System.NotSupportedException" is thrown at line 9255.

bridge.Connect(ip, 443);

To correct it, just change two lines (in Form1 line 9242 and 9243):

Socket bridge = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress ip = GetIPOfHost (_host);

To:

IPAddress ip = GetIPOfHost (_host);
Socket bridge = new Socket (ip.AddressFamily, SocketType.Stream, ProtocolType.Tcp); 

Please fix

This does work right because i started the proxy server and when i connected to it. it just closed or i would get an error from the web browser. i have tried my iphone connected to it and that falled, then i tried my android phone that falled and then i tried my windows computer and that falled. if you could tell me what i am not doing right or fix it that would be nice

Ability to rotate outgoing IP dynamically
