Posts: 22              For complicated reasons I won't go in to right now, I 
need to write a simple web proxy. Here's what I've come up with so far:

1. ServerSocket1: Listens on port 8080. This accepts incoming web requests from 
the browser.
2. ServerSocket1.AddSocket:
Code:return new ClientSocket
3. ClientSocket: Custom Class whose super is TCPSocket
4. ClientSocket.DataAvailable:
Code:
//Get the HTTP request sent by the browser
Dim data as string = Me.ReadAll

//Filtering stuff will go here
//...

//Create the socket which will connect to the proxy server
Me.Web = new WebSocket

//Give the proxy socket a reference back to this socket so it can send the data 
back to the browser
Me.Web.ReturnSocket = Me

//Connect to the proxy
Me.Web.Address = "localhost"
Me.Web.Port = 8081
Me.Web.Connect

//Forward the browser's request to the proxy
Me.Web.Write(data)

5. WebSocket = Custom Class whose super is TCPSocket
6. WebSocket.DataAvailable:
Code:
//Read the response from the proxy
Dim data as string = Me.ReadAll
//Write the response back to the browser
Me.ReturnSocket.Write(data)

7. WebSocket.ReturnSocket: TCPSocket to refer back to the socket to write the 
response from the proxy

This works perfectly well for simple sites like Google. The problem is with 
more complicated sites, in which cases most of the page fails to load and I get 
errors in Safari's Activity window. Is there a better way to do this?
