Nodejs proxy script, does not work with mod_deflate

Question

I created a small proxy node script that looks for request.url and either passes the request to my apache server, or uses node for the process / response to this request. So far I have been successful, everything works fine, but when I turn on mod_deflate for apache, "weird things will happen."

It appears that node simply “cancels” or “stops” the early response method. I am listening to the data event from my request, and at some point node just decides that the answer has ended (which is wrong) and fires the end event.

Code snippet:

var apache = http.createClient(82, 'localhost');

function pass_to_apache(req, res){
    var request = apache.request(req.method, req.url, req.headers);

    req.addListener('end', function() {
        request.end();
    });

    req.addListener('data', function(chunk) {
        request.write(chunk);
        sys.puts('writting chunk\n');
    });

    request.addListener('response', function(response) {
        res.writeHead(response.statusCode, response.headers);
        response.addListener('data', function(chunk) {
            sys.puts('writting data..\n');
            res.write(chunk);
        });
        response.addListener('end', function() {
            sys.puts('end of request');
            res.end();
        });
    });
}

var MainServer = http.createServer(function(request, response) {
    sys.puts('received '+request.method+' '+request.url + "\n"+JSON.stringify(request.headers));
    if(/^\/node/.test(request.url)) {
        response.writeHead(200, {'Content-Type': 'text/plain'});
        response.end("Hi, it node =)\n");
    }
    else if(/^\/exit/.test(request.url)) {
        sys.puts('closing..\n');
        MainServer.close();
        throw new Error('forced');
    }
    else {
        pass_to_apache(request, response);
    }
});

MainServer.listen(80, 'typeofnan.com');
