Http Content-Encoding Vs Transfer-Encoding

content-encoding 有三种gzip，compress，deflate，都是压缩算法content-transfer-encode ,只有一种chunking.

在response header中:

Content-Encoding :      ------>HTTP compression,request header-->Accept-Encoding: gzip, deflate
Transfer-Encoding :


"  Transfer-Encoding: chunked
当不能预先确定报文体的长度时，不可能在头中包含Content-Length域来指明报文体长度，此时就需要通过Transfer-Encoding域来确定报文体长度。通常情况下，Transfer-Encoding域的值应当为chunked,表明采用chunked编码方式来进行报文体的传输。chunked编码是HTTP/1.1 RFC里定义的一种编码方式，因此所有的HTTP/1.1应用都应当支持此方式。chunked编码的基本方法是将大块数据分解成多块小数据，每块都可以自指定长度.
