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.
