Another Filtering Proxy

[cattleyavns]

I just want to report a bug, that is we current cannot serve chunked Transfer-Encoding, I found this bug when I was uploading on https://dropbox.com, the upload progressbar show "2 secs remaining" but it always like this from the start, but without AFProxy the progressbar will always update itself (1min then 6 then 7 then 8 then lower..):

AFProxy: http://prntscr.com/9o8o1k
No Proxy: http://prntscr.com/9o8oms

I looks like "stream_to_client®" didn't use its "if need_chunked:" but stream the content normally, i tried to debug with

Code:

def stream_to_client(self, response):
        bufsize = 4096
        need_chunked = 'Transfer-Encoding' in response.headers
        written = 0
        while True:
            data = response.read(bufsize)
            if not data:
                if need_chunked:
                    self.wfile.write(b'0\r\n\r\n')
                break
            if need_chunked:
                self.wfile.write(('%x\r\n' % len(data)).encode('ascii'))
            print(data)
            self.wfile.write(data)
            if need_chunked:
                self.wfile.write(b'\r\n')
            written += len(data)
        return written

This page works very well (print a lots data): https://jigsaw.w3.org/HTTP/ChunkedScript
But not with Dropbox's Upload
