Simple proxy, using two QTcpProxy

[DmT021]

Sorry for my bad English.
I need to make a simple proxy (without auth, etc). Every connection must be in separated thread. It must transer data from/to browser and remote server.
My variant looks like this:
I have made a class Server (: QTcpServer), with overloaded incomingConnection
When incomingConnection emitted, I create new object of class Transfer, which create a new thread.
In new thread I create an object of class TransferHandler, which create two sockets(named in and out) and connect signals readyRead from in to slot inReadyRead, from out to outReadyRead. When these signals emited, I just copy data from one into another (using readAll()).
When signals disconnected() emitted, I just close sockects an delete objects.
In method run() of thread object I call method exec().

Problem --
Answers for all requests are come. But in the browser there is only a part of answer(I think only first package was come). Then, the browser hangs in connected state, but did not gets data.

Source code:

PS:--
If try to transfer data without events(did not call exec()), but just in cycle and using waitForReadyRead() all data transfers in to browser/server, but there is very long ping.--

I went quickly through your code, some comments:

• it's not useful to spawn a thread each time, you might want to keep working in the main thread and using just signals / slots (will work nicely unless you have to scale drastically)
• as your transferhandler class is waiting on your socket, you'd rather connect signals and slots as son as you've created the objects (otherwise, you might lose some events)
• you mix synchronous (waitForxxx) and asynchronous, it's not easy to follow

So far, without compiling it, I didn't see any trivial issue, I might have a further look later.

Thanks, I'll rewrite code using only signals ans slots and paste sources here.

Ok. I've rewrote proxy.
http://dl.dropbox.com/u/3506908/transfer/SimpleProxy.zip
This archive contains a project, with partially working proxy. It works fine with GET reqests, but doesn't work with POST.
I get "400 bad request", when uploading file. And http://ping.eu/ping/ also doesn't work.
What is wrong?
