How does Proxifier work?

Question

As you know Proxifier is a program that allows network applications that do not support working through proxy servers to operate through an HTTPS or SOCKS.

It can handle any transmission from running applications. I want to know how it can do this and how I can write one like that.

You should rewrite the question if you really want go technical. And how this relates to [delphi]? — OnTheFly, Feb 02 '12 at 09:25

A socksifier defines a dynamic library with the same functions as the OS socket layer, but defined in such a way as to use a socks proxy. The program being socksified uses that library instead of the OS-supplied one for its network communication.

FreeCap is your way to go.

It's released under GNU General Public Licence and written in Delphi.

I scrutinized the source code and found out that some units are effectively Windows 95 centric. Unless you need Windows 7 spoon-fed code, it's written well and for educational purpose it's a valuable starting point. Why not harness it with VMWare? – menjaraz Jan 31 '12 at 08:51
`Dll` file is the most important part of this project. It doesn't work on Windows 7 and I can't access its source. So, how actually can I use it? – Kermia Feb 01 '12 at 11:20

Do you mean `inject.dll` and `proxy32.dll`? – menjaraz Feb 02 '12 at 08:44
Yes, inject.dll and proxy32.dll – Kermia Feb 07 '12 at 08:28

Assuming you have downloaded `freecap_3.18-src.zip`, they are available respectfully in src\inject and in src\proxy32. – menjaraz Feb 07 '12 at 08:35
