> Recently I meet with a strange proble when I manage to get the server
> response body in the "Transfer Encoding: chunked" mode:
> I couldn't get the corresponding chunk length in hexdecimal ! The details as
> follows:
> I use the "null-transform" plugin modified to just output the server response
> body, when the web server uses the "Transfer Encoding: chunked" header
> to transfer chunked data to user agent, eg, I request the web page:
> "http://www.qq.com/";, I just get the chunk body data, but get no chunk length
> in
> the hexdecimal format "383cb\r\n" before the chunk body data. the chunk body
> data is uncompressed and like as "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
> 1.0 Transitional//EN"
> "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>\r\n......."
> In addition, I capture the data packet using the Wireshark software, I sure
> that I see the chunk length "383cb\r\n" before the chunk body data
> "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
> "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>\r\n.......", it is
> a complete chunk response !
> I continue to check the code of null-transform.c, set a breakpoint at the
> function TSIOBufferBlockReadStart(), run ATS and debug it, when ATS stop at
> the breakpoint TSIOBufferBlockReadStart(), I print the return string of
> TSIOBufferBlockReadStart(), there is no chunk data length at the head of
> output string, which implies the api TSIOBufferBlockReadStart() has bug！
> Breakpoint 1, TSIOBufferBlockReadStart (blockp=0x89d6570, readerp=0x89d5330,
