Great it works now!

Did you consider using Lua and LuaSocket [1] instead of wxLua? I think
this would simplify the whole socket and proxy programming.

Here is some example code:

-- load namespace
local socket = require "socket"
-- create a TCP socket and bind it to the local host, at port 8080
local server = assert(socket.bind("*", 8080))

while 1 do
	-- wait for a connection from any client
	local client = server:accept()
	-- receive the line
	local line, err = client:receive()
	-- if there was no error, send a simple webpage as example
	if not err then
		client:send([[
<html>
  <body>
    <h1>Proxy Test</h1>
  </body>
</html>
		]])
		print(line)
	end
	-- done with client, close the object
	client:close()
end

If your browser uses the proxy (as HTTP proxy), it will send something
like "GET http://www.google.com HTTP/1.1". Then you can download and
process the webpage using LuaSocket and send the result with client:sent().

You can use LuaSocket with wxLua as well.
