Hi Guys!

I'm new to the twisted framework and I'm using it to write a simple HTTPProxy with rewrite capabilities.

While calling ProxyCiient.handleHeader method, it seems that Content-Length field is being added. Notice that I say "add" instead of "set":

    def handleHeader(self, key, value):
        if key.lower() in ['server', 'date', 'content-type']:
            self.father.responseHeaders.setRawHeaders(key, [value])
        else:
            self.father.responseHeaders.addRawHeader(key, value)

Look at this headers that I get if I use handleHeader method:

HTTP/1.1 200 OK
Content-Length: 3025
Content-Length: 53
Host: localhost:8001
Accept: */*
Server: Coco el servidor
Connection: close
Date: Tue, 07 Aug 2012 20:35:13 GMT
User-Agent: curl/7.19.7 (i486-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15
Content-Type: text/html

So question is, am I using it properly? I'm adjusting the content length field as the data changed.

Thanks in advanced, Daniel
