This is a tiny and highly experimental HTTP/1.0 proxy software that I have written to debug HTTP protocol & it's clients. It is very small and simple, yet useful to reverse-engineering purposes. It's interface is quite obvious. The Server frame controls the IP, port and connection limit of the proxy server. It also shows how many connections are active at moment. The Data Traffic frame shows in/out packets & bytes. Service frame allows you to stop, start and quit the proxy. These are the very minimalist controls for the very minimalist proxy server.

The interesting stuff begins at the Plugin frame. All the packet passed through this proxy server are forwarded to the selectable plugin module. By default, it is logger.dll. It simply saves every single packet into separate file, which uses the following name scheme: from_IP.from_port-to_IP.to_port.log (for example, 127.0.0.1.4322-127.0.0.1.21.log). The files can be ordered by their modification date in your file explorer, so you can track the entire session:

The logger.dll can be set up to include a sequence counter at the beginning of each packet and to output saved packets into some specific directory:

Plugin module is also capable of injecting packets. Load the replicator.dll file and check the setup screen:

When you click the Capture button and then make some action in your proxied web client, the replicator plugin will prompt you if it got a corresponding packet. This packet may be resent automatically, at the period specified in the Period box. You can capture & replicate several packets, and manipulate their resend period. A very interesting application of the replicator plugin is to flood web chats and to spin up web counters. Of course, the right way is to use logger.dll and to make a clone that imitates the "real" web client.

The final note: this is, and always will be, an alpha-state code. I do not develop this proxy application anymore. It is useful to me the way it is. But you can grab the source and make a whatever plugin you like, or even rewrite the code entirely. I don't care. Just give me the proper credits!
