Create a proxy means that your application need to act as an HTTP Server when talking to the clients (the browsers) and act as a browser when comunicating with the web sites. The proxy opens a port for the server socket (for example port 90) and accepts the browser request on this port, than connect the web site (generally on port 80) and forward the request to the site server. The proxy waits for the server response, read it and after send the response to the client. The proxy changes the messages header if needed ( for example change the port in the url). In general proxy are multi thread applications, so they can manage more request in the same time.
